摘　　要：为了提高固体火箭发动机试验装配效率及准确性,以Creo软件为平台,研究了虚拟装配技术在试验中的应用。主要介绍了试验工装三维建模过程、虚拟装配方法,并通过干涉检测分析方法检测了试验结果、工装设计。通过在某型号固体火箭发动机壳体外载荷试验中应用表明,该方法不仅可以模拟试验装配流程,验证工艺流程的合理性,而且可以对试验结果进行干涉检测,推动了固体火箭发动机试验数字化的进程。In order to improve the assembly efficiency and accuracy of test for SRM, the application of virtual assembly technology in the test is studied in this paper. The three-dimensional modeling process and virtual assembly method of test tooling are introduced, and the assembly results and tool designing are tested by mean of interference detection.The application in external load test of various kinds of SRM shell shows that this method can not only simulate the assembly process, verify the rationality of the process, but also interfere with the test results. Virtual assembly can promote the digitalization of SRM.
