To reduce the vibration of helicopter rotors/fuselages, a frequency tunable hydraulic anti-resonant vibration isolator was proposed.The dynamic analysis indicates that by adjusting the stiffness of the pneumatic spring the anti-resonant frequency of the vibratioin isolator can be tuned.Furthermore, a genetic algorithm was used to optimize the structural parameters of the isolator in order to obtain lager vibration isolation bandwidth under the condition that the anti-resonant frequency is constant.
