Abstract：A method of active-passive hybrid vibration isolation virtual prototype on rotating machinery is provided and the simulation results of virtual prototype are verified by experiment. Firstly, the model of active-passive hybrid vibration isolation of diesel engine set is established. Then the output force characteristic of electromagnetic actuator is obtained by combining theories and experiment. Secondly, the active-passive hybrid vibration isolation virtual prototype of diesel engine set is established by combining ADAMS and MATLAB/SIMULINK. And the shock and sway characteristics, control algorithm and active-passive hybrid vibration isolation are studied on the virtual prototype. Thirdly, six hybrid vibration isolators are used to set up a diesel generator active-passive hybrid vibration isolation experimental prototype, and hybrid vibration isolation experiment is conducted. The results of experiment and simulation of hybrid vibration isolation are coincident approximately and the virtual prototype can be taken as an important base for designer of hybrid vibration isolation system.
