In view of the problem that traditional crawler tractor walking system is vulnerable to severe vibration, a new type of visco-elastic suspension mechanism has been developed. Using the complex stiffness theory, the differential equations of motion of the mechanism are established, and the stiffness-damping characteristics of the mechanism are analyzed. According to the viewpoint of energy conversion, the influence of static and dynamic viscoelastic damping materials on vibrational energy conversion rate was analyzed. The stiffness curve design and performance analysis of the developed 40kW crawler tractor viscoelastic suspension were carried out. The performance of the actual product was tested on the electro-hydraulic servo testing machine
