| 摘 要： | 提出了周边桁架可展天线展开过程的一种轨迹设计方法.通过优化方法选择贝塞尔曲线作为驱动索的输入运动轨迹,保证了展开角加速度的连续性并有效降低其峰值,从而达到了减小天线所受冲击的目标.通过数值仿真对比得出结论,天线的展开过程应是一个无中间匀速状态的先加速后减速过程.

| Abstract: | A deployment trajectory design approach of the hoop truss deployable space antenna is proposed.Optimization method is used to select Bezier curves as the input motion trajectory of driving cable,which guarantees the continuity of deployment acceleration and efficiently reduces the peak value.As a result,the impact on antennas is reduced.Numerical simulations demonstrate that the deployment should be an acceleration-deceleration process without mid-uniform-speed period. |
