Research on multidisciplinary virtual prototype application technology for complex electromechanical product based on COSIM platform

In order to solve the accuracy problems of a space navigation system- consisting of both mechanical and electrical parts-under the influence of the multidisciplinary coupling factors, based on COSIM platform we have implemented a multidisciplinary collaborative modeling and simulation. Under such background, this paper introduced system mechanism and development mode based on COSIC platform. And then, the paper focused on the development process based on COSIM platform, which includes the high level modeling, single discipline modeling, collaborative simulation debug. Virtual prototyping results show that this suite of methods can fully meet the needs of multidisciplinary simulation. In the further research, we will implement multidiscipline design optimization and algorithm of auto variable step.
