Conceptual Design and Simulating Research Based on Virtual Prototype Technology for Parallel Machine Tool (PMT)

Xu Guo, Z.X. Wang, Lezhong Wang

Abstract

A design process of PMT virtual conceptual design is put forward, and a design platform of PKM virtual prototype is developed based on ADAMS; By analyzing topological structure and classifying the functional module of the existing PMTs, a modular component base are built. The management of component base and virtual assembly of PMT are realized. A method to analyze kinematic properties of parallel mechanism is introduced by taking screw theory as guidance and taking virtual prototype technology as verifying tool. With the method, DOFs of parallel mechanism are vividly depicted and rationalities of actuation scheme are judged.
