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.
