| 摘 要： | 采用非线性有限元分析方法，对某光学遥感器反射镜的球铰支撑结构进行了建模。将罚函数的摩擦形式引进到摩擦接触对中，得到了较精确的分析结果，并与全固定支撑方式下的结果进行比较，表明球铰支撑静态环境下的工作更稳定。

| Abstract: | A mathematical model is established for the ball-hinge support of the reflector in an optical remote sensor with nonlinear FEM analysis.The friction form of penalty function is introduced to the frictional pair,and more precise results are obtained which are compared with that of whole fixed support to demonstrate the more stable operation under the ball-hinge support. |
