摘　　要：将柔性铰链技术应用于弧矢聚焦晶体单色器中的聚焦研究,在对柔性铰链结构参数研究的基础上,建立起了基于柔性铰链的压弯驱动装置行程与压弯动态半径之间的数学模型,分析了影响压弯半径分辨率的主要因素,并且将这种压弯模型成功应用在上海同步辐射装置(Shanghai Synchrotron Radiation Facility,SSRF)弧矢聚焦晶体单色器研制项目中。检测结果表明,依据这种压弯模型能够实现弧矢聚焦功能,并达到聚焦光斑性能指标。Hinge technology is used to study focusing behavior of a sagittal focusing crystal monochromator. A mathematical model describing the relationship between actuator displacement and dynamic bending radii has been established by studying geometry parameter of the hinge. Influential factors on resolution of the bending radii were analyzed. The model has been successfully applied in developing a sagittal focusing crystal monochromator for the SSRF （Shanghai Synchrotron Radiation Facility） project. The testing result indicated that focusing spot of the sagittal focusing crystal monochromator achieved satisfactorily the design requirement.
