Yue Jiong;Yu Cungui;Wang Guoliang;Xiang Weicheng;School of Mechanical Engineering, Nanjing University of Science & Technology;  
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.
