Zusammenfassung:The invention discloses an implementation method of a vibration table integrated with a shock excitation module and a virtual prototype. Through the MATLAB algorithm-based programming process, a transfer function/user-defined function extracted via the interface of the virtual prototype is adopted as excitation transformation characteristics (provided with a dedicated database). After that, the transfer function/user-defined function of a road excitation spectrum extracted via the virtual prototype and conveyed from a vehicle wheel to a connection point of a vehicle body and a vehicle suspension is adopted as an excitation conversion function. In this way, the road excitation is converted into the excitation at the connection point of the vehicle body and the vehicle suspension. Therefore, the excitation test for vehicles on a vibration table is enabled without any extra suspension system.
