Workspace Analysis of a Novel 4-DOF Parallel Mechanism

Yonggang Li

Abstract

The novel 4-DOF parallel mechanism of 2PRS-2PUS can be applied to build up highspeed milling equipment for large structure component.The workspace analysis is the basic task for parameters design.First of all,based on the topology analysis,the inverse kinematics of this mechanism is set up.In addition,the border of workspace is derived by using the theory geometric enveloping.Furthermore,the variations between the area of the fixed-orientation workspace and the orientational are solved by using the numerical method and provide the guidance for further research of the design of parallel mechanism.
