摘      要：Influence of multiple structural parameters on the performance of a gun launch system driven by highpressure reactive gases is important for structural design and performance adjustment.A coupled lumped parameter model was utilized to predict the propellant combustion,and a dynamic finite element method was applied to approximate the mechanical interactions between the projectile and the *** combustion and the mechanical interactions were coupled through a user subroutine interface in *** correctness and the capability of the finite element approximations in capturing small structural changes were validated by comparing predicted resistance with *** on the coupled model,the influence of structural parameters of a medium-caliber gun on the system performance was *** order to reduce the research costs,orthogonal tests were designed to investigate the comprehensive effects of the *** to statistical analysis,the important order of the structural parameters on the launching process was *** results indicate that the influence of the width of the rotating band stands out among the studied parameters in the *** work provides a method to investigate the influence of multiple parameters on system performance and gives guidance for controlling the system performance.
