By installing an elastic suspension on the bulldozer, it is possible to effectively dampen the vibration shock generated by the walking mechanism.As a viscoelastic polymer material that can efficiently dissipate vibration energy, the rubber vibration damping pad has excellent damping properties. Due to the inherent viscoelastic properties of the rubber material, the design parameters of the vibration damping pad should be based on the rubber used. The material properties and operating conditions of the bulldozer are determined.
