Rubber Wire Mesh Wheel Structure Damping Characteristics Analysis

In view of tracked engineering vehicle vibration, noise and othercharacteristics, using the advantages of traditional rubber isolator and steel wirerope vibration isolator, made of rubber steel mesh combined isolation pad, andapplied it to the bulldozers of the supporting wheels.According to the bulldozer working environment, rubber wire meshmaterial properties and the stress of the roller, design the rubber wire mesh typeroller shape size, in order to ensure its good mesh and crawler board.Taking a certain type of crawler type bulldozer as an example, establishedthe whole and single bogie wheel vibration damping model. All of the roller areintegrated for further analysis the whole damping cushion, and deduced roller tothe system frequency response function.This theme analyzed the viscoelastic material and wire mesh structurecharacteristics, energy dissipation principle and related parameters whichprovide a theoretical basis for the rubber wire mesh support wheel damping.Because the roller is a new type of structure which is not used in practice. Itis necessary to verify its mechanical properties, using the finite element softwareto the structure roller in three different load strength analysis, the results showthat the structure of the roller under different load all can meet the strengthrequirement.In order to test the supporting wheels damping buffering effect of thissupporting wheels. In view of the ground operation, uphill work,single rollersupport working conditions, compared respectively the structure of the rollerand traditional rigid roller in damping the simulation. By analyzing, the bufferdamping effect of the rubber wire mesh type roller is better than the traditionalrigid roller, especially in the natural frequency of vehicle near, rubber wire meshtype roller buffer effect more apparent.
