This paper proposes an integrated navigation method that integrates inertial navigation system (INS), global navigation satellite system (GNSS), and visual navigation system (VNS). Utilizing data from onboard sensors, this method merges relative navigation information from feature tracking of multiple UAVs with each UAV’s absolute navigation data. It includes specially designed transmission rules to reduce data exchange between UAVs. Each UAV uses an adaptive unscented Kalman filter (AUKF) method, which is enhanced into a collaborative AUKF (C-AUKF) using a message passing-based approach. Experiments in a simulated mission scenario revealed that the C-AUKF, in comparison to using extended Kalman filter (EKF), significantly improved flight test performance across the entire testing area, with a cumulative deviation of only 10.22 m, about 0.85% of the total flight distance. These results demonstrate that the proposed method not only meets accuracy requirements for position and velocity in integrated navigation but also significantly enhances multi-UAV navigation precision, particularly in scenarios with global positioning system (GPS) interference.","PeriodicalId":20558,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the compact design and relative motion between various parts, it causes wear in parts thus leakage introduce between various moving parts which work under tight tolerance. Multiple faults in an axial piston pump occur simultaneously after a long time of operation due to harsh working conditions and heavy loads. Faults in the pump deteriorate the pump’s performance and limit the operating range of the pump. Estimation must account for random and uncertain characteristics, and accurate wear prediction is difficult. Effective diagnosis improves pump dependability and performance. An approach based on simulation is utilized to model the impact of faults like leakage through eccentricity in piston-cylinder arrangement with increasing severity of clearance between piston-cylinder arrangement and its effect on the pump performance. As the clearance with different eccentricity between the piston and cylinder arrangement increases, outlet pressure and discharge of the pump remains unaffected up to a critical value of severity. After further increasing severity, outlet pressure and discharge reduce monotonically and saturate at a single value in extremely severe conditions. With increasing the severity of eccentricity in the piston-cylinder arrangement and increasing the severity of clearance, a critical threshold value shifts to a lower magnitude.","PeriodicalId":20558,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finding this compromise requires the resolution of a bi-level optimization problem (the respect of some specific constraints involves solving other optimization sub-problems). In this paper, we propose a novel approach for the optimal dimensioning of a two-degrees-of-freedom manipulator arm, where the objective function is defined by the minimization of the structure’s overall mass. The constraints that are taken into consideration can be divided into three categories: geometrical (bounds on design variables, admissible limit of the static deflection at the endpoint of the effector), kinematic (bounds on joint velocities and the accelerations of the actuators), and dynamic (admissible limit of the dynamic deflection at the endpoint of the effector). To achieve the penalizing dynamic configurations in terms of actuator torques and dynamic deflection, a quasi-static deformation model and a recurrent dynamic model were used. The static and dynamic deflection constraints are treated as optimization sub-problems, where their outcomes are integrated, at each iteration, into the global optimization process. The validation of the developed quasi-static deformation model as well as the proposed optimal dimensioning approach is conducted by comparing results with Ansys software simulations. Notably, The proposed approach demonstrates a significantly faster computation time compared to the Ansys software (06 s for the proposed approach vs 21 h for Ansys). Even though Ansys software performs optimal dimensioning for an imposed trajectory.","PeriodicalId":20558,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The distinctive properties of natural fibers make them readily substitutable for synthetic fibers. A substantial one million tonnes of fiber waste, primarily composed of paddy straw fiber, is generated globally. The research emphasis revolves around the adoption of the Waste to Wealth technique, a highly efficient process aimed at repurposing waste materials. This approach plays a pivotal role in curbing air pollution, specifically by preventing the incineration of the residual portion of paddy straw fiber on agricultural lands. The study involves the collection of paddy straw fiber from agricultural fields, with subsequent extraction facilitated by an extracting machine. Employing a chemical treatment process enhances the adhesion properties between the fiber and matrix. Consequently, comprehensive fiber tests, including the single fiber test, fiber tenacity, and fiber fineness, were meticulously examined for both treated and untreated fibers. The reinforcements and matrix were taken by the weight percentage of 50:50 with different fiber length (25, 50, 75, 100 mm) using the compression moulding machine with 300 mm × 300 mm × 3 mm dimensions.

Firstly, a multi-scale convolutional module was developed to extract fault features at different scales. Secondly, a multi-channel attention mechanism was proposed to enable the convolution layers of different convolution kernels fully extract feature information. Finally, a hybrid domain adaptation was constructed to dynamically extract invariant features from both the source and target domains.

If rolling bearing faults are not diagnosed promptly, it may cause huge economic losses. Bearing fault diagnosis can avoid catastrophic accidents, ensure the reliability of equipment operation, and reduce maintenance costs. Existing intelligent bearing fault diagnosis methods have fast diagnosis speeds and excellent fault recognition capabilities, which is not feasible for most important mechanical devices because of the difficulty in obtaining fault samples for training. To tackle this problem, a two-stage bearing fault diagnosis method without fault sample training based on fault feature knowledge is proposed. In the first stage, a fault detection vector is constructed based on signal statistical indicators. The Mahalanobis distance of the feature vector between online signals and historical normal signals serves for anomaly detection. In the second stage, based on the bearing fault knowledge, envelope spectrum fault indicators are proposed to form diagnosis vectors. By calculating the similarity between the diagnosis vector and the present fault label, the probability of different fault types will be obtained. Three experimental analyses show that the method is effective in detecting early faults and achieves high fault identification accuracy. The above results advantageously prove that the method can be used for fault diagnosis without fault sample training, and has the possibility of practical application.","PeriodicalId":20558,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce the undesirable effects of this phenomenon, in this work a practical control method to decrease these effects is presented. This control method ensures permanent joint contact and follows the desired path based on the actuators in the system. As a result, because the controller seeks to achieve two control demands using one actuator, these mechanisms are known as an under-actuated system. For this purpose, an improved second-order sliding-mode controller (IS-SMC) is proposed. This choice is based on its robustness and its ability to meet control demands in a finite time, as well as its high accuracy for sub-excitation systems. In this research, the control method is applied to the crank-slider and the four-bar mechanisms. For this purpose, at first, the equations of these mechanisms have been expressed in an ideal form, and then the nonlinear equations have been extracted with the imperfect joint. The Lankarani-Nikravesh and the Ambrosio models have been used for modeling the clearance and friction force in the joint, respectively.

Aiming at the problems of low working efficiency and high energy consumption of this kind of robot, a multi-objective adaptive trajectory planning method combining path optimization and trajectory optimization is proposed to improve the working efficiency of the robot and reduce energy consumption. Firstly, based on kinematics and dynamic analysis considering friction, the energy consumption model of robot trajectory is constructed. Then, according to the posture of the key points in the known workspace, the optimal path points in the joint space are obtained by a path point solution method considering the joint load characteristics. On this basis, a multi-objective model considering running time and energy consumption is established to plan the interpolation trajectory of the joint space of the quintic B-spline curve. Finally, constrained by the velocity, acceleration and torque of the joint of the manipulator, the optimal solution is obtained by using the elite non-dominated sorting genetic algorithm (NSGA-II), and the optimal weight factor is selected by a multi-objective adaptive optimization method to obtain the optimal position-time series. The experimental results show that compared with the quintic polynomial trajectory optimization method, the energy consumption of the proposed method is reduced by 10.90% under the same working efficiency.
