基于响应面法的某火箭炮结构参数优化

为提高火箭炮的射击密集度和射击稳定性，对基于响应面法的某火箭炮结构参数进行优化。引入响应面法，建立以弹管间隙、发射时间间隔以及闭锁力为设计参数，高低、水平方向的中间偏差为多重响应目标的响应面近似模型。模拟设计参数与响应目标强非线性关系，对近似模型进行回归检验，确定近似模型的可行性。利用建立的近似模型结合满意度函数法优化高低、水平方向的中间偏差，使其综合最优。结果表明：该方法能大大缩短仿真优化时间，且误差非常小，能达到提高射击密集度的目的。

Structural Parameters Optimization of MLRS Based on Response Surface Method

In order to improve the firing accuracy and stability of multiple launch rocket system(MLRS), the response surface method is applied to structural parameters optimization for MLRS, and built the approximated response surface model, which used windage, launch time interval and locking force as design parameter, and used the central bias of vertical and horizontal direction as multi-response target. The strong nonlinear relationship between the design parameter and the response target is simulated, and regression test has been done on approximate model, to make sure the approximate model is workable. Finally, check out the most reasonable solution of the optimization on central bias of vertical and horizontal direction, which combined approximate model and satisfaction function method, to improve the dispersion. The results show that the method can greatly shorten the simulation time and the error is very small, and can achieve the purpose of improving the fire accuracy.
