摘　　要：为了在地面模拟某型航天器低重力工作环境,设计了一种基于悬吊法的低重力试验装置,为航天器提供俯仰和滚转两个自由度的同时平衡航天器自重。采用有限元法对试验装置的关键承力部件进行了强度、刚度分析,并对主要部件进行了模态分析。结果表明,文中设计的试验装置强度、刚度均满足试验需求,关键部件低阶模态对被试产品无影响,为试验装置的设计和试验的开展提供了理论支撑。In order to simulate the low-gravity working environment of a certain type spacecraft on the ground,this paper designs a test device based on the suspension method,which provides two degrees of freedom for the spacecraft to pitch and roll while balancing the spacecraft's own weight.The strength and stiffness of the key load-bearing parts of the test device are analyzed by the finite element method,and the modal analysis of the main components is carried out.The result shows that,the strength and stiffness of the test device designed can meet the test requirements,and the low-order mode of key components has no effect on the test product.The results provide theoretical support for the design of the test device and the development of the test.
