摘　　要：采用刚柔耦合的方法,对某新型车载防空多管火箭炮进行了通过垂直凸台、水平壕沟、陡坡等极限路况的行驶动力学仿真研究。建立了越野车与防空多管火箭炮的刚柔耦合动力学模型,并考虑轮胎的作用,计算了越野车前后轮通过垂直凸台的极限高度和水平壕沟的极限宽度,建立各种极限路况的计算模型,对车载防空多管火箭炮进行了行驶动力学仿真,得到全系统的动态响应,为新型防空火箭武器系统的研制、试验提供了理论支持。The driving dynamics of evhicle combined with a new multiple launch rocket system for air defense was studied by applying the method of coupled rigid and flexible bodies.Simulations of passing over vertical boss,horizonal trench and steep slope were carried out.The model of coupled rigid and flexible bodies for vehicle and rocket launcher was established,with the tires taken into consideration in the model.The extreme height of vertical boss and the extreme width of horizonal trench were calculated,and the computing models for various extreme road surface conditions were developed.The driving dynamics simulation was performed and the dynamic responses of the whole multiple launch rocket system were obtained.The results can be used as a theoretical foundation for development and test of the new multiple launch rocket system on vehicle for air defense.
