摘　　要：支架作为航天器上仪器、阀门等元件的重要固定方式,支架动响应结果直接影响到固定于支架上的设备元件的性能,在振动力学环境下装有仪器设备或者阀门等元件的支架与空支架的动特性有较大差别。以传感器模拟件支架为研究对象,通过试验分析和有限元分析,根据试验结果对支架设计进行改进,为带有传感器等负重的支架动力学研究提供一种方法。The Bracket is an important fixed form for devices and valves in rocket. The dynamic response of the bracket affects the performance of the devices. The dynamic responses of the brackets with or without fixed devices or valves are of great difference in the vibration environment. This paper chooses the bracket with fixed sensor as the research object. Through test analysis and the finite element analysis, the design of the bracket is modified, and the paper provides a method for researching the dynamic response of the bracket with loads, such as sensor, etc.
