Description

technical field

[0001] The invention relates to the field of vibration control, in particular to a frictional energy recovery shock absorber with inner and outer double-layer shock absorbing structures. Background technique

[0002] The principle of the dynamic vibration absorber is to add a mass spring resonance system to the vibrating object to transfer the system resonance from the controlled system to the vibration absorber structure. According to the damping characteristics, it can be divided into two types: no damping and damping. In order to better control the vibration amplitude of the new resonance frequency due to the addition of the vibration absorber, the current vibration absorber is often of the damped type. Due to the different damping structures, it can be viscous damping, frictional damping, structural damping and so on.
