摘　　要：为研究油气悬架发射车在全轮支撑状态下导弹起竖时的动力学特性,采用了基于ADAMS/Simulink/AMESim的联合仿真方法。建立了ADAMS发射车的虚拟样机模型、AMESim油气悬架系统模型和四级起竖液压缸模型,设计了Simulink起竖模型的控制策略,并以Simulink为平台,通过各软件的联合仿真接口实现了联合仿真研究。仿真结果表明:随着导弹起竖过程的进行,各级油缸能够依次伸出,在启动、换级、停止时产生较大的冲击;连通式油气悬架相比于独立式油气悬架能更好的分配各轴载荷,保持车体平衡姿态;起竖到某个位置时,油缸对起竖臂的力由推力变为拉力。To research the dynamic response of erected process for missile launcher under the full tire supporting conditions,the co-simulation model was established by using ADAMS / Simulink / AMESim software. Multi-body dynamics model with ADAMS,hydropneumatic suspension model and telescopic four-stage cylinder model with AMESim,control strategy and co-simulation platform with Simulink were built based on co-simulation technology. The results show that the four-stage cylinder can be extended one after another and there are obvious vibration when the hydro-cylinder is started,changed level or stopped. The interconnected hydro-pneumatic suspension can effectively distribute different axle loads and keep the launcher car balance. The force that cylinder applies to arm changes from thrust to tension when the missile reaches a certain position.
