Abstract

Aiming at the low firing accuracy problem of tank on the move caused by hull vibration under the condition of high-speed and uneven surface road, using the muzzle vibration to characterize firing accuracy, a dynamic model for tank firing on the move was established based on multi-body system dynamics, vehicle-terramechanics and gun launch dynamics. The three-dimensional road surface spectrum file considering the left and right track unevenness coherence was written by means of the sinusoid superposition method. Through the dynamics analysis of the hull vibration, some of the proposals for reducing the influence of hull vibration were presented. The results show that the hull vibration can be divided into linear vibration and angular vibration. The linear vibration is very sensitive to the changes of speed and road surface level and can be effectively reduced by integrating the control device into the suspension. The angular vibration is more sensitive to the changes of the pavement level than the speed. Through the optimization design of fire system and introducing modern control theory into the current stabilizer, angular vibration effect can be effectively reduced. The result provides a certain reference to understand the muzzle vibration rule and improve the firing accuracy of on-the-move tank.
