摘　　要：　研究了平面3-DOF机构的基本构型及应用.用图论理论,推导出了平面3-DOF运动链的全部基本构型,并给定3个驱动元件均在机架上的约束条件,以减少惯性力的作用.得出5种实用的平面3-DOF机构的基本构型.对得出的每一种基本构型分析其结构特点,应用现状,提出了潜在的应用前景.The basic configuration of planar 3Degree of freedom (DOF) kinematic chains and its application were studied. Taking graph theory as a mathematical model, all possible basic configurations of planar 3DOF kinematic chains were derived. The constrained condition is that three drive elements should be fixed on the frame at the same time to decrease inertia. Five kinds of applied basic configuration of planar 3DOF mechanisms were obtained. Structure characteristics and application status were analyzed, and potential application prospects for their basic configurations were presented.
