A script-driven virtual assembly simulation system based on assembly sequence concurrent planning

Abstract

In the design cycle of produce, virtual assembly can help to improve design quality and reduce assembly cost. A script-driven virtual assembly simulation system based on assembly sequence concurrent planning is proposed. The architecture of script-driven virtual assembly simulation system is set up. In this architecture, assembly script language and script interpreter is the key functional module. Virtual assemble sequence concurrent planning algorithm is given to generate the assembly script language. Script interpreter is used to realize the assembly process simulation. Because the assembly sequence can be generated automatically and revised flexibly, the script-driven virtual assembly simulation system can be used for training system that allows training supervisors to create training instructions and allows trainees to learn assembly operations. The description of keywords and grammars in script language and the virtual assembly sequence concurrent planning algorithm based on the inversion of concurrent disassembly sequence are presented in the full paper. Machine vice and PECVD equipment are two applications in the script-driven virtual assembly simulation system. Their description codes of script language and assembly concurrent sequences are given, which shows the feasibility of the script-driven virtual assembly simulation system.
