Parameter revising method for a rigid-flexible coupled virtual prototype of a multibody system containing impact

The concept and application of virtual prototype technology were simply presented here, and the veracity of a complex multi-body system simulation was analyzed. A rigid-flexible coupled virtual prototype model of a complex multi-body system containing impact was built with multi-body dynamics software Virtual Lab, and the correctness of the virtual prototype simulation was evaluated combining with the test data. Some key system parameters were revised by using the sensitivity and perturbation methods, the scattering level of the simulation results had better consistency with that of the test ones, and the reality of the virtual prototype model was improved.
