Abstract

Abstract

The slenderness ratio of a rocket-assisting torpedo is relatively large, and its connecting structure is complex and multiform. This study proposed a dynamic simulation modeling method for a rocket-assisting torpedo. The detailed modeling of the connecting structure was simplified, including the wedge ring, thrust block, and clamp. The modal of the rocket-assisting torpedo was calculated and the mode vector was extracted. The mode shape slope of the inertial measurement component installation position was calculated too. This study provided an analysis method to design input parameters for the attitude control and the determination of the installation position of the inertial installation component.
