[Abstract]:Under the premise of high volume loading fraction, how to improve the structural integrity of solid rocket motor is the main problem in the optimization design of solid rocket motor. Based on particle swarm optimization algorithm (PSO), a fast optimization design method for 3D solid rocket motor (SSRM) was proposed, and the parametric modeling of a 3D solid rocket motor (SRM) was realized by using PCL, a secondary development tool of MSC.Patran. Without changing the volume loading fraction, PSO algorithm and genetic algorithm (GA) are used to complete the optimization design of the engine configuration. The results show that both of the two methods can meet the requirements of optimization design, but the computational time of PSO algorithm is 42 shorter than that of GA algorithm, and the proposed method can quickly realize the optimization design of solid rocket motor. Improve the structural integrity of complex three-dimensional solid rocket motor.
