对SAST 5000平台的碳纤维内埋框架及相应结构板设计和试验进行了研究。对内埋框架结构进行了拓扑优化并采用碳纤维材料,分析了优化的结构板模态和静力状态,并对整板进行了静力试验及探伤。结果表明:在方案阶段金属材料内埋框架贮箱安装板的基础上,通过对内埋框架结构形式的拓扑优化及碳纤维材料的使用,大幅减轻了贮箱安装板重量,仿真分析及摸底试验说明碳纤维内埋框架贮箱安装板力学性能满足卫星承载要求。

The design and test of spacecraft bearing plate usually adopts metal embedded framework to improve the bearing capacity when being required to support large load. The SAST 5000 platform tank bearing plate＇use metal embedded framework in the conceptual stage. The weight of tank bearing plate is reduced greatly through the use of topology optimization and carbon-fiber material on the embedded framework. Through simulation analysis and test, it proves that the mechanical properties of carbon-fiber embedded frame bearing plate satisfy satellite carrying requirements. It presents design and testing of the carbon-fiber embedded frame and the bearing plate in this paper.
