摘　　要：本文根据自行火炮系统的结构及运动特点 ,用多体动力学理论的Kane Huston方法建立了自行火炮的全炮多体系统动力学模型 ,分析了射击时的作用力 ,考虑了行进时地面对车轮及系统的约束作用以及履带对车体振动的影响 ;对该模型在射击力及地面激励作用下的响应进行了计算 。Based on the structural and movement properties of the self propelled gun, digital simulation of firing on the move of a self propelled gun is systematically introduced. By analyzing the forces acting on the gun, a complex multi body system model of the self propelled gun is extablished by the Kane Huston method, in which the constraints on the wheels and the effects of the chain are described in detail. The firing forces are calculated by use of interior ballistics theory and analysis of automatic systems and the force caused by the running of the gun and the roughness of the road are also calculated. By applying these forces to the multi body model, the response of the gun is solved. Then the initial perturbation of the projectiles can be calculated taking into consideration vibration of the muzzles, and finally the firing accuracy is solved and discussed.
