基于混合FE-SEA方法的航天器支架车声振响应影响分析
The response of bracket vehicle of spacecraft based on hybrid FE-SEA method
摘要
Abstract
The bracket vehicle is an important brace facility in the acoustic test of spacecraft, and it is important to study how to use this facility for the spacecraft vibro-acoustic predication. Based on the hybrid FE-SEA method, different cases and vibro-acoustic models are established for spacecraft, and the effect of the bracket vehicle on the vibro-acoustic response of spacecraft is analyzed. The simulation results show that the bracket vehicle mainly affects the responses of low-order modes of the system, and its effect on the high-order modes could be neglected. This conclusion can be a guidance for the simplification of a complex spacecraft vibro-acoustic model.关键词
