Research on Vibration Tension Control of High-Speed Tracked Vehicle Systems

Addressing the vibration issues during the operation of high-speed tracked vehicles, a dynamic tension control method based on an electro-hydraulic servo system is investigated, along with a comparative study of two tension control strategies. Based on the force analysis of the idler wheel and curved arm, a theoretical model for tension near the idler wheel is established. The accuracy of this theoretical numerical model is verified by comparing it with the results of multibody system dynamics simulations conducted in RecurDyn. A co-simulation platform for electro-hydraulic servo control is built using the software interfaces of RecurDyn, Simulink, and AMESim to tune the PID control parameters and achieve dynamic tension control of the track. Simulation results indicate that the root mean square value of the track plate displacement is reduced by 18% when using the PID control strategy, and by 33.3% when employing the fuzzy PID control strategy. Furthermore, the track tension approaches the ideal value. The data suggests that the hydraulic tension control strategies studied in this paper can effectively reduce the vertical displacement of the track plate, thereby lowering the risk of track damage and enhancing the smoothness and reliability of the driving process.
