The simulation of the rigid-flexible coupling model of the tank firing on the move based on fully flexible body modeling method

Abstract

Generally, the rigid-flexible coupling model based on the modal reduction method cannot realize the contact between the rigid body and the flexible body. Based on the multi-body systems dynamics and fully flexible body modeling method, the rigid-flexible coupling dynamics model of the tank gun system was constructed. Then by combining with the PID control model, the mechanical/control co-simulation model of the tank gun on the move was constructed. The influences of the control system and vehicle speed on the muzzle vibration during the shooting process were respectively analyzed. It has been shown that the control system model can effectively simulate the response characteristics of the muzzle during the move of the tank. Under the same road surface and the same control law, the frequency and amplitude of the muzzle angular displacement in the low frequency range increase with the increase of the vehicle speed. The constructed model and the simulation results are of great significance to the analysis and optimization of the shooting accuracy of the tank gun on the move.
