Abstract:The existence of various CAE engineering software improves the simulation efficency. And in the simulation process of mecha-
nical product, the integration of function modules of various engineering software is the key problem to realize simulation task flow.
Based on the analyzing of WFMC criterion, with the thought ponent development which improves the flexible and extensible of
system, abstract ponent through the reality need, ponent based simulation workflow modeling platform is imple-
mented, by using EMF, GEF technologies and Java language, and the status-express mechanism in process executing is briefly introduced.
Finally, static simulation flow model of a mechanical product is built with the platform, and its valid
