Abstract
The influences of multiple structural parameters on interior ballistics were investigated by using an orthogonal test method. 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 barrel. In order to reduce the research costs, orthogonal tests were designed to investigate the comprehensive effects of the parameters. According to statistical analysis, the important order of the structural parameters on the launching process was obtained. The results indicate that the influences caused by the width of the rotating band stand out among the studied parameters. This is an extended abstract of a paper published in Defence Technology, 2019.
