A linear stability analysis method is proposed for the evaluation. The strategies include active trailer differential braking, active trailer steering and variable geometry approach. A linear 3 degrees of freedom (DOF) yaw-plane car-trailer model is generated for the controllers' design and a nonlinear 21-DOF yaw-roll car-trailer model is developed in CarSim to validate the stability control strategies by means of numerical simulations. To determine the stable motion boundary, eigenvalue analysis is conducted for identifying the vehicle critical speed. The linear quadratic regulator technique is applied to the design of controllers for active trailer braking, active trailer steering and variable geometry strategies. It is revealed that the active trailer braking strategy is feasible and effective for improving the lateral stability of car-trailer systems. Simulation results demonstrate the effectiveness of the linear stability analysis method.","PeriodicalId":35145,"journal":{"name":"International Journal of Vehicle Systems Modelling and Testing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/ijvsmt.2019.104874","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66698185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The EV powertrain system performance test bed is applied for the tests. Applying a LiFePO4 battery (192 V/100 A·h) as the research object, a calculation method is developed for battery charging/discharging efficiency. Tests are performed to analyse the influence of battery temperature on terminal voltage, as well as the influence of battery SOC and charging/discharging current on the battery efficiency. Applying an AC asynchronous motor (rated power 32 kW) as the research object, tests are performed to analyse the influence of battery voltage on the performance of motor system, the efficiency characteristics of drive motor within the high-speed field weakening area, and the efficiency characteristics of drive motor in normal working conditions. Through the tests and analysis for the performance of EV battery and motor, it can provide guidance for the matching of EV powertrain system, and gives basis for development of high-efficient EV control strategies.","PeriodicalId":35145,"journal":{"name":"International Journal of Vehicle Systems Modelling and Testing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45712284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A concept of twist beam axles has been idealised as a beam model with extensive parametric variables. With this model many stiffness and kinematic characteristics which are typically required for twist beam axles can be determined analytically and accurately within a few seconds. Compared to the conventional method with numerous CAD and CAE iterations this new method can substantially reduce the development time, including human resources and computation time. Several axles have been evaluated and verified. The results are well comparable with those of CAE simulations. This very fast and efficient concept development can be coupled with mathematical optimisation algorithms in order to obtain an ideal starting position for further CAD/CAE-based product development in detail.","PeriodicalId":35145,"journal":{"name":"International Journal of Vehicle Systems Modelling and Testing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47055578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the literature survey done in this research, it shows that the design methodology of tubular space frame was not performed explicitly, so there is a great need to fill this gap. Therefore, this research aims to develop a methodology for designing tubular space frame of vehicles and in other applications. A finite element model was made to evaluate torsional stiffness of vehicle frame then the model results were validated with experimental data obtained from a previous experiment. A parametric study was conducted using this model to investigate the impact of varying tube cross sections, length ratio, triangulation, intermediate sections and materials on both frame stiffness and frame stiffness to weight ratio. From this study, several guidelines for designing tubular space frame were concluded and a design methodology for tubular space frame was deduced.","PeriodicalId":35145,"journal":{"name":"International Journal of Vehicle Systems Modelling and Testing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44866060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The IDCs make use of a brake system and rear steering system. A fuzzy logic control method and a sliding mode control method were employed to design the three systems. The performance of the ARS and IDCs was tested under a variety of road and driving conditions. The results show that ARS and IDCs systems tracked the reference yaw rate under all tested conditions. Two IDCs reduced the body slip angle also. When a vehicle ran on a split-μ road and brake input was applied, IDCB and IDCR virtually eliminated the lateral dynamics. These results indicate that two IDCs enhanced lateral stability and preserved steerability.","PeriodicalId":35145,"journal":{"name":"International Journal of Vehicle Systems Modelling and Testing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46141533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study compares multiple e-bikes configurations and presents to the reader scientific criteria to choose the one that fits best for non-trained cyclists, who want to use e-bikes for everyday transportation in cities with steep roads, assuring that the cyclist takes effective part of the power input. Power development, speeds, energy consumption and efficiency result from a mathematical model and experimental data. Configurations vary in motor placement, assistance level, cyclist cadence, wheel type and transmission sets. Results indicate that the motor's placement is the most determining factor in the efficiency of the entire system. Placing the motor in the bottom bracket, allows both the cyclist and the motor to range in the most efficient rpm. As efficiency for the middle drive motor is higher than the hub drive motor, energy consumption in the hub drive motor is 18% higher.","PeriodicalId":35145,"journal":{"name":"International Journal of Vehicle Systems Modelling and Testing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47571303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The subsequent solution of the equations of motion can lead to simulation in real-time. Presently, real-time simulation models based on multibody dynamics can account for a large number of rigid and flexible bodies as well as contact descriptions. It enables the inclusion of physical phenomena and user feelings associated with multibody systems in the real-time simulation. These specifications can be used in a number of product processes including user training and product development. The present study applies real-time multibody simulation to a three-wheel, two-ton counterbalance forklift. The forklift simulation model includes rigid bodies, joints, a contact model, friction forces, power transmission, and a steering mechanism. The study reports aspects associated with forklift performance such as speed, speed reduction around a curved path, mast wobbling, maximum lifting capacity, and vibrations during the lift. The simulation model is verified by comparing the speed, acceleration, mast lift and tilt speeds with the measurements of a reference forklift.","PeriodicalId":35145,"journal":{"name":"International Journal of Vehicle Systems Modelling and Testing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66698041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
