摘要：
In this paper, the concept and application of virtual prototype technology are simply introduced, and analyses the veracity program in course of complex multi-body system simulation. The rigid-flexible couple virtual prototype model of complex multi-body system including collision is built, and the veracity of virtual prototype simulation is evaluated combining limited test data. Updating some typical system parameters by sensitivity method and perturbation method, it makes the simulation results have better consistency with test results, and improves the simulation precision of virtual prototype model.
