摘要

为研究车载防空导弹行进间连续发射的安全性与发射精度，考虑车架柔性建立三轴轻型高机动发射车的刚柔耦合动力学模型，并构建不同标准等级路面模型，以此开展发射车发射动力学分析。经与实车跑车试验结果比对，验证了动力学模型正确性，通过对多路面不同车速的行进间发射动力学仿真，获得车体振动与导弹出筒姿态数据。研究结果表明，行进间发射时车速应根据路况等级采取相应限制，用以提高车体行驶稳定性及降低载弹振动响应；路面不平所导致的初始扰动变化具有随机性，但大部分工况下导弹出筒仍具有低头趋势，在导弹偏航基础上发射筒体结构对导弹具有一定纠偏作用；在车路因素及多速度的耦合作用下，风载荷对导弹出筒姿态的影响较小可忽略。

Abstract

In order to study the safety and launching accuracyof vehicle-mounted anti-aircraft missile continuous launching on the move, the rigid-flexible coupling dynamic model of launch vehicle was established. The flexibility of frame was considered and different standard grade pavement models were constructed. The accuracy and rationality of the modelling method proposed by this paper were validated against the test results of real vehicle. The dynamic simulation of vehicle on different roads with different speed was carried out to obtain the vibration and outlet attitude data. The results show that the vehicle speed should be limited according to the road conditions, which could improve the stability of the vehicle and reduce the vibration response of the missiles.The initial disturbance caused by uneven pavement is random. In most cases, the missile still has a pitch tendency when exiting the launch barrel, and the launch tube has a certain effect on missile deviation correction on the basis of missile yaw. The influence of wind load on the outlet attitude of missile is small under the coupling action of vehicle-road factors.
