该文从武器全系统弹、炮、药、环境一体化的角度 ,在多管火箭发射与飞行动力学的理论研究的基础上 ,形成了多管火箭随机发射与飞行动力学数值仿真系统。对某多管火箭振动特性、动力响应及射击密集度等进行了数值仿真 ,仿真结果得到了一系列试验验证。由仿真系统仿真得出的某多管火箭武器密集度试验方案减少了试验用弹量 82 .5%。

By studying the theory of launch and flight dynamics of Multiple Launch Rocket System (MLRS) from the point of whole system including launching device, rockets, propellant and environment, the simulation system of random launch and flight dynamics of MLRS is established. The simulated results of vibration characteristics, response, and dispersion of MLRS in launching process are verified by series of tests. A new method acquired from the simulation system has reduced the number of rockets used in dispersion test for one MLRS by 82.5 %.
