摘　　要：为了分析不同因素对车载导弹系统行进间发射动力学影响,利用虚拟样机技术,对车载导弹行进间发射过程进行模拟分析。基于Adams平台建立了系统的刚柔耦合动力学模型;采用IFFT方法对不同等级路面进行数值模拟;考虑左右轮相关性,得到了不同等级路面模型;进行了不同车速和不同路面等级下车载导弹系统行进间发射动力学仿真,得到了导弹出筒姿态结果。仿真结果表明,车速越大,导弹出筒姿态越恶劣;路面情况越差,导弹出筒姿态越恶劣。In order to analyze the influence of different factors on the launch dynamics of the vehicle-mounted missile system, the virtual prototype technology is used to simulate the launch process of the vehicle-mounted missile. Based on the Adams platform, a rigid-flexible coupled dynamic model of the system is established. IFFT method is used to simulate different grades of pavement. Considering the correlation between left and right wheels, different grades of pavement models are obtained. After the launch dynamics simulation, the results of the missile exit attitude are obtained. The simulation results show that the higher the vehicle speed, the worse the missile exit attitude;the worse the road conditions, the worse the missile exit attitude.
