摘要
利用自回归(AR)模型对不同等级随机路面进行数值模拟,建立了车载防空导弹的行进和发射一体化多柔体动力学模型。根据行驶动力学仿真结果,确定了最恶劣发射时刻。结合分析结果完成了行进间发射动力学仿真,获得了导弹姿态参数。分析了路面和车速对防空导弹行进间发射精度的影响。研究结果表明,B级路面上3种车速均能安全发射,C级路面上车速受限于25 km/h.
The numerical simulations of different grade random roads are carried out using autoregressive （AR） model, and the travelling and launching integration models of vehicle-mounted antiaircraft missile based on flexible multi-body dynamics are established. According to the simulation results of vehicle dy- namics, the worst missile launching time is established. The launching dynamics simulation is conducted and the missile attitude parameters are obtained based on the analyzed results. The effect of velocity and road condition on launching accuracy is analyzed. The research results show that all the three vehicle speeds on B-grade road can ensure launching safety, but vehicle speed on C-grade road is restricuted to 25 km/h.
