Aiming at the problems of low efficiency, poor global search and complex process in optimization design of internal ballistic parameters of mortar, a process integrated optimization design method was proposed based on the mortar interior ballistic model. Firstly, MATLAB/Simulink software was used to build the mortar interior ballistic model and the mortar bore pressure and velocity curve with time were obtained through simulation calculation. The obtained bore pressure and velocity parameters were in good agreement with the test results. Then, through the integration optimization platform ISIGHT integrated with MATLAB/Simulink software, combined with the improved non-dominated sorting genetic algorithm with elite strategy, a multi-objective optimization design with the maximum bore pressure and muzzle velocity as the objective function was carried out. The optimization results show that the maximum bore pressure is reduced by 13.63% and muzzle velocity is increased by 10.46% after optimization. This method not only improves the performance of interior ballistics but also improves the optimization efficiency, which provides a new idea for the optimization design of weapon interior ballistics.
