Modeling and Simulation of Multi-body Dynamic for Rocket-Assisted Torpedo Separation
摘要
Abstract
This paper analyzes the structure and force of the multi-rigid-body system composed of vehicle and separating cabin, establishes a Lagrange equation of multi-body dynamic model, and then simulates the motion state of the com-bined system in a given initial condition by fourth-order Runge-Kutta method. The multi-body dynamic models are veri-fied by comparing the simulation results with the test ones. This study may provide a basis for safety analysis of the separation process of rocket-assisted torpedo.关键词
