[0002] In order to solve the vibration isolation problem between the vehicle body and the chassis, the existing technical solution uses an elastic suspension connection between the vehicle body and the frame. In the early stage of vehicle development, only the design of elastic suspension vibration isolation is considered, but in the later stage of vehicle development, dynamic vibration absorbers have to be used to solve certain specific vibrations.

Since the maximum point of the frame torsional and bending vibration modes is basically located in the middle part of the frame, which is also the connection part of the body suspension, the frame torsional and bending vibrations are transmitted to the body through the suspension. Excitation from the ground and tires will also cause resonance of the frame torsional and bending modes, causing body resonance under high-speed driving conditions, seriously affecting driving comfort.

A through hole is arranged in the middle of the upper base plate 6 for the rods of the connecting bolts 4 to pass through, and the rubber member 8 is bonded between the upper base plate 6 and the lower base plate 7. The rubber member 8 is in a circular ring shape, and the heads of the connecting bolts 4 are located in the rubber member 8. The lower end of the rubber member 8 has a notch structure corresponding to the head position of each mounting bolt 5 for placing the heads of the mounting bolts 5.

[0035] Working principle: The mass block 1 has a specific mass, and the elastic element 2 has a specific stiffness. The two constitute an elastic vibration system of a specific frequency, which can absorb and eliminate the resonance of the vehicle body at a specific frequency, can solve the resonance problem of the vehicle body assembly at a specific frequency, and help improve the driving comfort of the vehicle.
