该文中的卫星采用新型框架面板式构型,该构型卫星与运载采用新型四点连接的方式,而不是传统的包带连接方式。对该文中的卫星进行模态分析及试验,采用不同的安装基础进行多次模态试验,找出其中的差异,并进行相关比对分析。根据分析及试验获得框架面板式卫星的模态特性,判读卫星的模态特性是否满足运载要求,同时根据试验结果完善相关航天试验规范。
The satellite in this article uses a new frame panel configuration, which uses a new four-point connection to the satellite rather than the carrier, rather than the traditional strap-to-strap connection. The modal analysis and experiment of the satellite in this article are carried out. Several modal tests are conducted on different installation bases to find the differences among them, and the correlation analysis is carried out. According to the analysis and experiment, the modal characteristics of the panel panel satellites are obtained, and the modal characteristics of the satellites are satisfied to meet the requirements of the carrier. At the same time, the relevant aerospace test specifications are improved according to the test results.
