Study on Kinematical Characteristics of 2PTT-TPT Parallel Machine Tool Based on Virtual Prototype

Abstract

This paper proposes a new 2PTT-TPT parallel machine tool, solves the kinematics equation and analyzes the actuating force and maneuverability. In order to simulate the movement trajectory and pose, the model of virtual prototype is built in Solidworks and visualNastran. As a result, the mechanism is featured by compact construction, no singularity and good maneuverability, which provides the theoretical foundation for the design of parallel machine tool.
