Numerical Simulation of LHA Deployment in Loop Antenna

摘要: 作为环形天线实现锁紧和释放功能的关键部件，抱环组件的展开特性是评价天线展开过程的一个重要指标。针对环形天线抱环组件的设计要求，进行了抱环组件展开过程的数值仿真。仿真结果显示：通过展开铰链中驱动弹簧和缓冲弹簧的优化匹配，可以实现抱环组件初期迅速展开，末期缓慢锁定的功能要求。

Abstract: As an important part to realize the lock and release function of loop antenna, the deployment characteristic of LHA (Launch Hold-Down Assembly) is a very important criterion to evaluate the deploying process of loop antenna. According to the design requirement, we conduct numerical simulation of the deployment of LHA. Simulation results and analysis show that requirement of the LHA to release quickly and stop slowly can be easily achieved by appropriate combination of the stiffness of drive spring and stop spring.
