Problems solved by technology

Most of the existing vibration isolation mechanisms are based on the use of bionic nonlinear X-shaped vibration isolators on the basis of the excellent characteristics of low-frequency vibration isolation. This vibration isolation mechanism has a good vibration isolation effect, but this vibration isolation There are still some disadvantages in the mechanism, one is that its vibration isolation frequency band is relatively narrow, which reduces the vibration control ability, and the other is that the bionic nonlinear X-shaped vibration isolator itself has poor ability to absorb vibration amplitude (it is not conducive to reducing the resonance amplitude ), can only rely on buffering to gradually decompose and transform the amplitude. This structure is more used in static or relatively stable environments, which is not conducive to achieving the expected vibration reduction effect on moving objects. Therefore, a vibration isolation and vibration absorption is developed. The integrated nonlinear vibration control structure can avoid the above problems, and it is very in line with actual needs
