Abstrakt: Optimization research of firing interval is applied to improve firing density level of MLRS. Firstly, the finite element model of MLRS is built to obtain the dynamic response of the launch guider muzzle and the rocket initial disturbance is calculated. Secondly, the equation of exterior ballistic is solved using Monte Carlo simulation and Runge-Kutta method and with mathematical statistic method the estimate of dispersion is obtained. Thirdly, modal analysis for MLRS is carried out and the new firing interval is proposed combined with the dynamic response obtained above. Finally, substitute the new firing interval into the model of MLRS, the results show that the new firing interval shorten the firing time by 21.4% and improve the firing density effectively without affecting the dispersion of the MLRS.
