Abstract

This work aims to studying a method on decreasing the muzzle vibration and improving the firing accuracy of move tanks under the influence of stabilizer.s Based on a PID control method, the paper simulated the vertical stabilizer of a tank in MATLAB/Simulink environment.A dynamic model of tank on the move was established based on the multi-body system theory, vehicle terramechanics and gun launch dynamics.Then through the RecurDyn/Control module, the electromechanical coupling dynamics model of moving tanks was established.The muzzle vibration characteristics of tanks on the move were analyzed.The numerical calculation results show that the hull vibration is the major influence on the muzzle vertical angular displacement of tanks on the move.The vertical stabilizer can control the vertical vibration of the cradle effectively.However, the muzzle vertical angular displacement is still greater than cradle’s significantly.It is not conducive to guarantee the stability effect of the stabilizer.By using the muzzle vertical angular displacement as control target of the vertical stabilizer, the muzzle vertical angular displacement can be reduced effectively.It can improve the stabilization accuracy.The research can provide certain reference for improving the firing accuracy of tanks under the condition of high mobility.
