The development status of vibration absorber and the working principle of vibration absorber are introduced .For the limitations of non-adjustable nature or the discrete adjustable nature of the passive vibration absorber 's dynamic parameters , the vibra-tion absorbing equipment is designed by changing the effective length of a cantilever beam to make the dynamic parameters continuously adjustable.When the resonance frequency is changed , the damping effect is analyzed on the primary system .The results show that the equipment can effectively absorb vibration for the main structure in a certain shifting frequency range .
