Aimed at the problems that students' opportunity of practical operation in the course of Computer Assembly during vocational education is so few that they cannot master the skill of computer assembly, this paper solved it by establishing computer assembly virtual simulation platform. This paper mainly introduced how to realize the design and production of computer assembly virtual simulation platform through Eon studio and pro/e tools. To carry out experiment teaching by using computer assembly virtual simulation platform is a new development direction because it promotes the revolution of teaching form, teaching method and teaching concept. Meanwhile, it can effectively solve difficulties in teaching and enhance the quality of experiment teaching.
