冲击响应谱在卫星运输冲击响应分析中的应用
Application of shock response spectrum in analysis of satellite transportation shock response
摘要
Abstract
The dynamics environment during satellite transportation exhibits some randomness and uncertainty,which may bring hidden troubles to the safety of satellite transportation.At present,there is neither universal satellite transportation simulation method in engineering nor guiding mechanical environmental conditions for transportation analysis.In this paper,two typical ramp shock signals that can often be caught during satellite transportation were extracted,and finite element model of satellite and its support structure for transportation was established based on ABAQUS software.The analyses of transient response and shock response spectrum(SRS)were conducted respectively.The results show that,compared with transient response analysis,SRS analysis saves 95%of the computing load with a deviation of not more than 17%,as well as implements an envelop for the maximum stress response,indicating that SRS analysis may better meet the demand of fast and accurate simulation in satellite engineering practice.关键词
