In this paper, aiming at the problem of excessive low-frequency noise in a minibus, the SEM (Super Element Method) was applied to the NVH (Noise, Vibration and Harshness) dynamics simulation analysis of the vehicle, and the vibration and noise control schemes were proposed from the aspect of vibration transfer path to improve NVH performance. First, the relationship and difference between SEM and LFEM (Legacy Finite Element Method) were elaborated theoretically. Afterward, the legacy finite element model of the full vehicle, which comprehensively considered all related components such as BIW (Body In White), chassis, door covers, body accessories and interior and exterior trims, was established based on LFEM. Furthermore, the subsystems of legacy finite element model of the vehicle were divided into super elements based on SEM, and the differences between SEM and LFEM in model processing were discussed in detail. In addition, the modal analysis and frequency response analysis of the full vehicle were carried out by LFEM and SEM respectively, and the computational results were compared with the testing results to verify the simulation accuracy and feasibility of the SEM in solving the vehicle body dynamics problems. Meanwhile, through the comparison of simulation analysis process of SEM and LFEM in practical case, the advantages of SEM compared with LFEM were discussed in terms of computational efficiency and storage space occupied. Finally, the stiffness optimization schemes of rubber bushing in the middle of driveshaft were proposed to improve vibration and noise from the aspect of vibration transfer path, and the testing results verified the effectiveness of the optimization schemes in reducing the low frequency noise inside the vehicle. The study concluded that SEM had obvious advantages over LFEM in terms of computational efficiency and storage space occupied, while ensuring the computational accuracy basically consistent with that of LFEM.

“…In this paper, the considered RMES assume their use in crop production. One of the main complex indicators determining the overall technical level of the RMES is productivity, energy efficiency, positioning accuracy [19,20]. However, these criteria depend on individual indicators of the RMES, such as: operating weight; operating power of the engine; transmission type; type of propulsion; features of kinematics of rotation; the location of the control station; the degree of automation of control; the adaptability of the engine to overcome dynamic fluctuations in resistance, navigation characteristics, and so on.…”

To assess the effectiveness of the robotization of mobile energy means (RMES), it is necessary to consider many quality criteria and functional limitations that characterize the work of RMES (operational, economic, functional, etc.). The formation of quality criteria allows us to justify the effectiveness of the robotization of MES, the improvement of the multi-criteria optimization apparatus and the software package for performing optimization calculations considering the aspect of robotization of mobile power facilities for agricultural purposes in crop production. However, unfortunately, most of the quality criteria cannot be formalized, that is, it is not always possible to establish mathematical dependencies of these quality criteria on variable parameters. In this regard, the purpose of these studies is to solve the problem of assessing the weight of each quality criterion and functional limitations, including using expert methods

“…Results indicated that the cabin suspensions with dynamic isolators had the best vibroprotective properties. 11 Tiago Priolli Monteiro and Antonio Carlos Canale built a direct-dynamic model by starting from the vehicle's equation of motion and utilizing MATLAB Simulink's basic toolbox. This dynamic model was mainly used to calculate the vehicle's longitudinal forces, verify the driver's inputs, and test gear selection algorithms.…”

This paper presents a detailed investigation about the effect of structural damping and modal truncation number on vehicle dynamic characteristics. Finite element method and experimental method are applied to research vehicle’s dynamic response. According to the real vehicle’s structure, the dynamic simulation model of vehicle is established by the substructure modeling method. In order to research the influence of different variables on vehicle’s dynamic responses, the control variable method is adopted. In other words, the parameters of structural damping and mode truncation number are changed respectively. Comparing the dynamic response results, the influence rules of structural damping and mode truncation number on dynamic responses are obtained. Results show that the dynamic responses of vehicle changes significantly with the change of structural damping and mode truncation number. The studying results provide important significance for the determination of parameters. As well as, the correctness and reliability of the analysis results are verified by the experimental method.
