Oriented to the structure system of small spacecraft, an integrated simulation scheme for small spacecraft series was proposed and a static & dynamic simulation platform with 7parameters was developed, based on ANSYS and Pro/E software packages integrated with Visual C language and secondary development languages of Pro/ TOOLKIT and APDL. The influence on structural performances of the side-wall thickness, the supporting board thickness and the installation board thickness was studied with the simulation platform. Aiming at light weight, optimal structuralparameters were determined by the analysis results, and a reasonable and reliable structure scheme of small spacecraft was proposed, of which the weight was reduced by 17.7%. Thus it provides a method and basis to the fast and reliable design of spacecraft.%面向一种小型空间飞行器结构系统,基于ANSYS和Pro/E,结合Pro/E和ANSYS二次开发语言Pro/TOOLKIT、APDL和VC,提出了针对系列小型空间飞行器集成化仿真的实施方案,并研究开发了7个参数的动静态仿真分析平台.基于该平台,研究了侧壁厚度、支撑板厚度、安装板厚度对结构性能的影响规律.以轻质化为目标,基于分析结果确定了较优的结构参数,给出了合理、可靠的小型空间飞行器结构方案,重量减轻了17.7%.为航天器的快速可靠设计提供了方法和依据.
