Computational modeling study reveals rotating band width dominates launch performance in medium-caliber guns, highlighting critical priorities for interior ballistic structural design.

Key Points

To evaluate the hierarchical influence of multiple structural parameters on the interior ballistics and launching performance of a medium-caliber gun system.
Coupled a lumped parameter propellant combustion model with a dynamic finite element model in ABAQUS to simulate projectile-barrel interactions, validating resistance forces against experimental data.
Designed orthogonal tests combined with statistical analysis to systematically assess the comprehensive effects of structural variations while minimizing simulation costs.
Determined the order of importance for structural parameters governing the gun launch cycle.
Identified the width of the projectile's rotating band as the most influential factor altering launch dynamics among the evaluated structural features.
