基于音圈电机的环形桁架结构主动悬吊方法
Method for active suspension of hoop truss structure based on voice coil motor
摘要
Abstract
The hoop truss structure is the basic structure of a satellite deployable antenna. In this paper, an active suspension method is proposed to unload the gravity of a hoop truss structure in the ground. In view of the fact that the voice coil motor can output an Ampere force with a large displacement, the tension at the suspension point is calculated by solving the static equation of the suspension system. Then, an active suspension test system is established. When the Ampere force output by the voice coil motor is equal to the tension, the structure is slung and the gravity is unloaded. Finally, the experimental results show that the first two orders of the frequencies of the structure with and without suspension are almost equal, and the modes are consistent. Therefore, the suspension method proves to be effective.关键词
