摘要
针对HJ-1A卫星发射状态的特殊性,使用有限元计算和相似性类比推算的方法,详细分析了正样状态HJ-1A卫星对于运载力学环境的适应性,得出HJ-1A卫星正样状态能够满足运载的力学条件的结论,并根据分析结果,改进了试验条件,最终通过试验验证,并顺利发射成功。
This paper provides an analysis and validation for HJ-1A satellite which is used to find a solution to adapt special dynamic environment by launch vehicle. Based on a reliable result of FEM analysis and comparability deduction, an optimized dynamic simulation test is performed. HJ-1A satellite is successfully launched, and the validity of analysis is proved.
