摘要
多管火箭密集度仿真是提高多管火箭射击密集度和减少多管火箭试验用弹量的前提。从武器系统弹、炮、药、环境一体化的角度,对多管火箭武器发射动力学进行了深入的理论和试验研究,建立了多管火箭武器刚弹耦合的多体系统发射动力学方程,应用多体系统传递矩阵法,实现了多管火箭动力响应分析,利用蒙特卡洛方法建立了多管武器系统密集度仿真技术。实例对某多管火箭武器系统密集度和减少多管火箭武器试验用弹量的优化方案的密集度进行了数值仿真,仿真结果得到了试验验证。
It is very important to simulate the precision of fire of Multiple Launch Rocket System (MLRS) for improving the dispersion and for reducing the number of rockets used in test. Launch dynamics of MLRS is deeply studied both in theory and through test from the view point of whole system including rockets, launcher, propellant and envirment. The launch dynamic equations of multibody coupling rigid bodies and elastic bodies of MLRS are established. The dynamic response of MLRS is analysed by using transfer matrix method of multibody system. The dispersion simulation technique of multiple tube weapon is established based on the launch and flight dynamic equations by using Monte-Carlo method. The dispersion of a MLRS and the programming test scheme to reduce rocket consumption in the MLRS test are simulated. The results of simulation are verified by test.
