摘　　要：将单轴直圆柔性铰链的理论应用于铰链机构的研究,建立起了四连杆铰链机构模型,应用到弧矢聚焦晶体单色器的压弯机构中。通过控制输入量输出小角位移,实现了同步辐射光束在弧矢方向的聚焦,分析了机构变形时需要输入的驱动力,在线测试聚焦光斑数据证实了模型的正确性。The theory of single-axis flexure hinge is applied to a four connecting rods hinge mechanism, which has been used on the sagittally focusing double-crystal monochromator at Shanghai Synchrotron Radiation Facility （SSRF）. It outputs limit angular motion with an inputting force. Mechanism system errors were analyzed by elastic deformation of mechanism, and inputting force was analyzed, too. Correctness of the mechanism has been validated in online tests of the focused beam.
