提出了一种新型正交五自由度并联机床，并对该并联机床进行了运动学分析。运动学和雅可比矩阵的5-对并联机床进行了运动学解析推导，定义了运动学传递指标和全局运动学传递指标，并利用物理模型技术对运动学图谱进行了分析，为并联机床的运动学设计提供了理论依据该新型五自由度并联机床可作为高刚度、高精度、高工艺效率要求的精密工作平台。
A novel orthogonal 5-DOF parallel machine tool is proposed,and the kinematics analysis of the 5-DOF parallel machine tool is presented.First of all,the kinematics and Jacobian matrix for the 5-DOF parallel machine tool were derived analytically.Then the kinematics transmission index and global kinematics transmission index were defined.Finally the kinematics atlases were analyzed by using the physical model technique.The results can provide theoretical basis for the applications of the 5-DOF parallel machine tool.The novel 5-DOF parallel machine tool can be used as the precision platform in which the requirements for high stiffness,high accuracy and good technological efficiency.
