Despite the widespread use of asynchronous electric motors (ED) in electric transportation, they often fail to meet high reliability requirements. This is primarily due to their operation in a wide range of rotational frequencies, variable load modes, frequent stops and starts, and challenging road conditions. These factors result in significant vibrations of traction asynchronous EDs, leading to reduced reliability and service life. Goal: The goal of this study is to develop methods to enhance the reliability and longevity of traction asynchronous EDs by improving the design and manufacturing technology of the stator housing and rotor of the electric motor. Methodology: Analytical research methods were employed to investigate approaches for improving the quality of traction electric motors for electric transport. Experimental research methods were used to determine the technical condition of EDs based on their vibrodiagnostic parameters. Statistical methods were utilized to process experimental data. Results: Vibration levels, which are indicative of the technical condition of EDs, were selected as the primary criterion for assessing their quality. The proposed design and manufacturing technology for asynchronous electric motors enable the following: increased manufacturing and assembly precision of EDs, simplified assembly process, reduced number of sorted parts during inspection and bearing replacement, and the development of an asynchronous traction ED with a power capacity of 90 kW and a rotational frequency of 3000 rpm, meeting class D requirements with permissible vibration levels. Originality: This study presents developed methods for increasing the reliability and longevity of traction asynchronous EDs through experimental approaches. The one-sided arrangement of base surfaces in the stator housing and the attachment of rotor bearing units enabled the production of a vertical ED assembly consisting of two independently controlled units: a housing with a shield and a rotor with bearing units. Practical Value: The achieved reduction in vibration levels allows for a predicted 2-3 times increase in the lifespan of the developed ED, depending on operating conditions. Furthermore, the created ED meets all environmental standards' requirements for vibration levels.","PeriodicalId":153826,"journal":{"name":"Vehicle and electronics.

Within testing, reliability testing under operating conditions comprises 58-73% of the workload. However, even after extensive testing, serially produced tractors often fail to meet the specified lifespan and reliability requirements. Final refinements are only made to tractors after a certain accumulation of operational faults, resulting in hidden defects remaining in the serial production of tractors, as testing primarily addresses major structural and manufacturing defects. Goal. The aim of this study is to evaluate the design and manufacturing quality of tractors based on their vibration characteristics. These characteristics can identify structural and technological defects that decrease the reliability and lifespan of tractors. Methodology. Analytical research methods were employed to improve the quality of traction electric motors for electric transportation. Experimental research methods and the determination of electric motor technical conditions based on their vibrodiagnostic parameters were utilized. Statistical methods were employed to process experimental studies. Results. Vibration measurement results indicated that tractors belonging to vibration class E are not recommended for serial production. These tractors have an estimated lifespan of 6-8 thousand engine hours and incur high maintenance costs compared to tractors of vibration class D. Tractors with vibration levels of class E are not recommended for serial production due to the excessive vibration load on components. Originality. The T-150K tractor family requires significant redesign of its structure, manufacturing processes for components, and bearing unit assembly. This is achieved through constructive measures, such as ensuring bearing preload in shaft supports, using class 4 precision bearings with a noise index of QE1, and providing a floating fit with a clearance of no more than 15 μm between the bearing and the housing. Introducing intermediate bushings into the design of gearbox output shaft bearings improves the accuracy of machining bearing seating surfaces and the assembly of bearing units. Practical value. The developed vibration evaluation methods for T-150K tractors enable the assessment of their design and manufacturing quality. The research data obtained during the design stage allows for more reliable predictions of tractor quality.","PeriodicalId":153826,"journal":{"name":"Vehicle and electronics.

One of the areas of developing energy saving when using machines and mechanisms is the recovery of used energy for the purpose of reuse. At the same time, potential energy accumulated by massive mechanisms or kinetic energy of moving machine elements is used. Goal. The purpose of the work is to reveal the main advantages and principle of operation of the pneumatic damping system for energy recovery and generation. Methodology. The methodological basis of the work is the analysis, comparison and generalization of existing scientific research and inventions. The ever-increasing interest of domestic and foreign researchers in the direction of energy saving in road transport, the steady expansion of the list of inventions related to energy saving, such as the conversion of mechanical vibrations into electrical, thermal, hydraulic and other types of energy with subsequent accumulation and useful use, were noted. Results. When the car is moving, as a result of the deformation of the suspension springs, there are transverse and longitudinal vibrations of the frame or body, which are damped by shock absorbers. The most widely used are hydraulic and gas shock absorbers, which use the resistance of a viscous liquid or gas when passing through calibrated holes or limited valve diameters. The very process of dampening oscillations is reduced to the transformation of mechanical energy into thermal energy with subsequent removal of heat to the environment. Originality. As part of energy saving, the authors of the work propose to accumulate the energy of oscillating movements in the form of pneumatic energy of compressed air with the possibility of further use in various systems of automobile transport. They also show the effectiveness and expediency of introducing similar measures, especially in hybrid schemes of cars in which the transformation of thermal and electrical energy takes place at the same time, point out the problems that arise when introducing energy accumulation in the form of compressed air, and propose measures to overcome negative phenomena that characteristic of this process.

The most effective energy management strategies for hybrid vehicles and electric vehicles are optimization-based strategies. These strategies require prior knowledge of the driving cycle, which is not easy to predict. Goal. The goal is to combine the Worldwide harmonized light vehicles test cycle (WLTC) with short trips on small sections with real traffic levels to predict the energy and fuel consumption of hybrid vehicles and electric vehicles. Methodology. Research methods are experimental and mathematical. First of all, eight characteristic parameters are extracted from real speed profiles used on urban road sections in the city of Kharkiv under various road conditions, as well as on short WLTC trips. The minimum distance algorithm is used to compare parameters and determine three traffic levels (heavy, medium, and low traffic) for short WLTC trips. Thus, for each route determined using Google Maps, the energy and fuel consumption of hybrid vehicles and electric vehicles are estimated using short trips by the WLTC, adjusted for distances and traffic levels. In addition, a numerical model of the vehicle was implemented. It was used to test the accuracy of predicting fuel and energy consumption in accordance with the proposed methodology. Originality. For the methodology using only GM information is required as input data; no other device or software is required. This aspect makes the methodology extremely economical. Then, the algorithm regulating traffic levels shown by GM is unique and valid in all urban centers. This aspect makes the methodology universal. WLTC takes into account the driving styles of drivers around the world, so the methodology can be applied to any car driver. Prediction accuracy can be increased by taking into account other input information, such as the distribution of traffic light signals or the driver's typical gear shifting style. Results. The results are promising, as the average absolute percentage error between experimental driving cycles and projected ones is 3.89 % for fuel consumption, increasing to 6.80 % for energy consumption. Practical value. The possibility of energy forecasting and fuel consumption for a hybrid vehicle and an electric vehicle makes it possible to develop energy consumption management systems for HEVs that can manage the energy reserve to ensure full travel by electric traction in limited traffic zone (LTZ) or minimize local air pollution; increase the service life of energy reserves (usually batteries) by maintenance costs and disposal problems reducing; optimize the transmission-use efficiency due to fuel consumption and pollutants emissions reduction.","PeriodicalId":153826,"journal":{"name":"Vehicle and electronics.

Strengthening requirements for reducing CO2 emissions requires reducing fuel consumption in cars with internal combustion engines. One of the ways to solve this problem is to equip cars with a hybrid power plant that combines an internal combustion engine and an electric motor. A classic hybrid vehicle requires two energy sources: a fuel tank for the internal combustion engine and a power battery for the electric motor. Therefore, hybrid vehicle has a more complex design and a relatively high cost. A mild hybrid vehicle is a new concept of a hybrid vehicle for urban use that is emerging today. Such MHVs have a simpler design and also allow you to save up to 30% of fuel in urban driving mode. Goal. The purpose of the work is to improve the economic and environmental characteristics of a mild hybrid car, due to the use of an inexpensive asynchronous electric motor with frequency control in the scalar mode, as well as more effective use of power plant control system algorithms. Methodology. Analytical research methods were used to develop algorithms for effective use of the power plant in acceleration, uniform motion, regenerative braking, and stopping modes. Mathematical modeling and calculation methods were used to justify the use of an asynchronous motor for the power plant of a mild hybrid vehicle. Results. The use of a low-power asynchronous motor in the power plant of a mild hybrid vehicle is mathematically justified. The use of the principle of rational amplitude-frequency scalar control is proposed. An algorithm and a scheme for the implementation of an induction motor control system with support for the optimal power factor have been developed. Originality. Instead of using a valve synchronous electric motor with an expensive control system, it is proposed to use an asynchronous motor, which has advantages in the power plant of a mild hybrid vehicle. An asynchronous motor will allow the use of effective algorithms of uniform motion and regenerative braking modes. Practical value. The design of a soft hybrid vehicle with the use of a low-power asynchronous electric motor makes it efficient and cost-effective. The scalar control method of an asynchronous motor, with the slip control, makes it possible to obtain a system with high control quality and lower cost of implementation.","PeriodicalId":153826,"journal":{"name":"Vehicle and electronics.

The problem of distributing competing flows of road users in time is prevalent worldwide, and there is no fully justified and intelligible solution, even if only traffic flows can be considered. At the busiest street intersections, the primary means of traffic management is traffic signal control. If the traffic lights are close to each other, then it is a good practice to coordinate the operation of such traffic lights to organise the most unhampered movement of vehicles in one or several directions; that is the progression. Goal. The goal is estimation of the time required to ensure the uniform motion of vehicle platoon progression on the coordinated artery of the city arterial. Methodology. The developed approach is based on the use of analytical research methods and allows to formalize the interaction of the platoon progression with additional vehicles. Results. The results of the estimation of the minimum time required to ensure the uniform motion of the platoon progression allow us to state that for actual speeds and vehicle accelerations when starting from the stop-line of the intersection, the requirement for the uniform motion of the platoon progression is too strict, especially if we take into account that advance time will increase significantly as the number of additional vehicles in the queue increases. Originality. Analytical models created using formulas of the kinematics of rectilinear uniform accelerated motion of a point make it possible to estimate the minimum advance time of the start of the traffic light signal due to the deliberate speed of traffic and the average acceleration of one additional vehicle when starting from the stop-line of the intersection.
