%X 建立了基于自由度约束互补集的三维可视化构型库。根据所需要的柔顺机构自由度，在可视化构型库中任意位置放置工作台，在该构型库中选择自由度空间和非冗余约束，再根据其它性能指标选择非冗余约束，得到具有最优性能指标的柔顺机构。为验证通过构型库设计柔顺机构的可行性，建立了一种两移动自由度柔顺机构微动工作台几何模型，并对该模型进行了有限元仿真分析。结果表明：通过该构型库组合的柔顺机构具有结构简单，解耦输出等优点。<br>A 3D visual configuration library was established. The designer can place stage in the freedom space in the visual configuration library according to the required DOF of compliant mechanism. Then DOF space and non-redundant constraints can be chosen intuitively. According to other performance indices, the non-redundant constraints are selected. Finaly, the compliant mechanism with the optimal performance indices is synthesized. In order to verify the validity and convenience of the visual configuration library, a compliant mechanism with two translational DOFs is synthesized. And the finite element method is used to analyze the compliant mechanism. The results show that the output of the compliant mechanism is decoupled and its structure is simple
