Abstract
In this paper, a computational simulation for the hybrid vibrations control of the supporting system is given, and the force feedback control mechanism is applied to the flexible isolation system, so the effects of the hybrid active and passive mount on the reduction power flow transmission are discussed, which show that the flexible isolation system can improve more substantially by use of the hybrid method in comparison with the passive isolation system alone in the whole frequency ranges, finally, the author thinks the hybrid method will be effective to reduce the diesel engine vibration and noise.
