含柔性部件星载天线的展开锁定冲击
内容简介:文章进行了某含柔性部件星载天线的展开锁定过程动力学仿真,将展开臂处理为柔性体,通过刚度等效获得了展开臂止动臂与锁定装置止动块之间的碰撞刚度。仿真结果显示,展开臂的瞬间锁定会在展开电机转轴处产生较大的冲击力矩,是展开机构设计时应该关注的重点。
Abstract:Dynamic simulation of a satellite antenna with flexible body is conducted,deployable beam of the antenna is modeled by flexible body,and the impact stiffness between the deployable beam and the lock mechanism is obtained by stiff-ness simplicity. Simulation result shows that,the transient locking of deployable beam will cause considerable shock momen-tum at the rotate axis of the deploy motor,and should be carefully treated in motor design period.
