In allusion to problems that the information from different systems is difficult to share and integrate, and the efficiency and precision of simulation are not sufficient at present, a time varying load course model based on co-simulation of multibody dynamics and finite element was put forward. The load files of multibody dynamics system were extracted, transformed and imported into the finite element analysis(FEA) system using ANSYS parametric design language (APDL) and macros. The curved surfaces were discretized into smaller unit mesh, and the node loads of the curved surfaces were calculated, discretized and loaded according the load distribution function and the surface shape. The co-simulation based on the heterogeneous system information of multibody dynamic and FEA was carried out, and the precision and efficiency of simulation were improved．
