针对传统铰链结构复杂、锁紧力小及展开基频较低的问题,为提高太阳帆板性能,利用带状弹簧的壳体屈曲性能,设计了易加工装配的简单铰链,具有质量轻、展开可靠、自动锁定及锁定力大等诸多优点。使用有限元软件分析了带状弹簧及铰链的力学特性,并进行了帆板展开动力学仿真,重点研究了太阳帆板结构基频,并推导了厚度和弯曲刚度对基频的影响关系。仿真结果表明,所设计的带状弹簧铰链用于帆板展开,满足系统对展开时间和展开基频的要求且基频优于传统铰链,可为航天器帆板展开机构设计提供参考。
Aiming at the problem of complex hinge structure, small locking force and low base frequency of deployment, a simple hinge with easy-to-assemble is designed to improve the performance of solar panels. Reliable, automatic locking and locking power and many other advantages. The finite element software was used to analyze the mechanical properties of ribbon springs and hinges, and the dynamic simulation of windsurfing was carried out. The fundamental frequency of the solar panel was studied emphatically and the influence of thickness and bending stiffness on the fundamental frequency was deduced. The simulation results show that the designed ribbon spring hinges are used for the windsurfing to meet the requirements of the system for the unfolding time and the unfolding of the fundamental frequency, and the fundamental frequency is better than the traditional hinges, which can provide references for the design of the spacecraft windsurfing unwinding mechanism.
