Abstract：This paper simply introduces the concept and application of virtual prototype technology, and analyses the veracity program of complex multi-body system simulation. The rigid-flexible couple virtual prototype model of complex multi-body system including impact is built with multi-body dynamics software Virtual Lab, and the accuracy of virtual prototype simulation is evaluated combining with the test data. Revising some key system parameters by sensitivity and perturbation method, the simulation results of scattering degree have better consistency with test results, and the reality of virtual prototype model is improved.
