摘要：

通过对绳索联动机构(CCL)进行等效简化，分析CCL同步展开机理，并建立数学模型。详细推导了含CCL联动系统的动力学方程，以某型太阳帆板展开同步性为例，仿真分析展开动力学过程以及大幅不同步产生的原因。以整个展开过程中最大不同步量最小为优化目标，建立联动系统优化模型，并采用序列二次规划算法（SQP）对驱动力矩参数进行了优化设计。相对驱动力矩为正值的传统设计方法,根部驱动力矩为负值的优化结果有效降低联动绳索负载，改善了太阳帆板展开同步性。

Abstract:

Based on the equivalent simplification of the closed cable loops (CCL), the principle of CCL synchronous deployment is analyzed and the mathematical model is established. The dynamic equation containing CCL is deduced in detail. Taking the synchronization analysis of a certain type of solar panels as an example, the dynamics of deployment and the cause of the large-scale non-synchronization are simulated and analyzed. The optimization model which is to minimize the asynchronous angle is set up and the parameters design of the driving torque is optimized by the sequential quadratic programming (SQP) algorithm. Compared with the traditional design method using the positive driving torque, the optimization results using the negative root driving torque parameters, reduce the loading of the linkage system effectively and improve the synchronous deployment of the solar panels.
