摘　　要：阐述了差式微位移放大机构的基本设计原理，分析了机构中位移损失的原因。研制的放大机构具有较好的放大效果，而且机构的位移输出线性特性也较好。采用片状柔性铰链成功地解决了由于机构中的位移干涉造成的机构内部反力太大的问题。The basic designing principle of a differential action microscopic displacement with flexure hinges is described. The geneses of displacement loss in the mechanism are analyzed. The magnifying mechanism, which is designed and made by ourselves, has a good magnifying effect. And the linear feature of displacement output is also good. The utilization of strip flexure hinges successfully solve the problem that the interior anti force is too large in the mechanism.
