ADAMS的全地形车载火箭炮行进间发射动力学研究

Dynamic Simulation Analysis of Rocket Launcher Launching on Move

利用多体动力学软件ADAMS、有限元分析软件ABAQUS建立了全地形车载火箭炮系统发射与行驶一体化动力学模型,基于路面功率谱密度函数和谐波叠加法,创建了全地形车野外行驶的三维随机土石路况模型,对战车行进间发射进行了动力学仿真。分析该型号车载火箭炮行进间发射的动力学特性,得到了战车及发射装置的动态响应情况及运动特性和车速对发射的影响规律。仿真结果表明,全地形车可以在土石路况低速行驶完成行进间发射任务。

Based on the multi-bodied dynamics software ADAMS and the finite element analysis software ABAQUS,the launching and driving integrated dynamics model of rocket system on all-terrain vehicle is built. The three-dimensional randomly earth-rock road model based on the power spectrum density function of the road and random number theory is created. Dynamic simulations for the launch on the move under different velocities on the same rank road conditions is completed. The dynamic response of the all-terrain vehicle and the launch device,and motion characteristics of the launch,the influencing law to the launching of the velocity and road condition factors are obtained. The research results show that rocket system could complete the mission on the move at low speeds.
