非对称构型的大倾角星箭弹簧分离装置动力学研究
Dynamics Study on Spring Separation Device of the Asymmetric Satellite-Rocket with Large Inclination
摘要
Abstract
In order to better control the motion state of the satellite and achieve precise orbit insertion,it is necessary to assess the sensitivity of the satellite to the physical parameters of the system during the satellite rocket separation process.This paper proposes a simplified two-dimensional dynamic model for the complex layout scheme of separation of large angle asymmetric star rocket joint surfaces,which simplifies the complex three-dimensional dynamic problem into a planar dynamic problem,reduces the system's degrees of freedom,and greatly simplifies the computational difficulty of the model.The simulation results indicate that by appropriately configuring the preload of built-in springs and interface friction properties,the initial attitude of satellite orbit insertion can be effectively controlled.The research results can provide guidance for the parameter design of satellite-rocket separation devices.关键词
