Research on the Initial Disturbance of Vehicular Missile with System Vibration Analysis

Abstract

This paper is based on the complex multiple vehicular missile launch simulation model, researches the influence of combustion jet flow to the initial disturbance of missile. It establishes rigid-flexible coupling dynamic model by use of Adams and Ansys, and calculates the value of combustion jet flow field in missile box by means of Fluent. The rigid-flexible coupling dynamic simulation for the whole launch process is carried out. The study results show that the simulation with loading jet flow can accurately tend to real launch environment, it has great significance to optimize the simulation and to improve the accuracy of the simulation.
