The principle of the lever type anti-resonant inertial resonant machine was analyzed, and the expression of the upper and lower mass body under anti-resonant inertial resonant machine was derived. Based on the anti-resonance theory, the anti-resonant frequency and dynamic load transmit rate of the resonant vibration isolation system have been obtained, meanwhile the parameters of the system was analyzed to get the influencing factors, which may be instructive to the practical application of the anti-resonant inertial resonant machine.
