Abstract
Under the action of low frequency and heavy load, the buffer components of construction vehicles easily occur thermal incubation, even thermal softening failure, due to the hysteresis effect and poor thermal conductivity of viscoelastic materials. In this paper, the buffer component of viscoelastic suspensions used in a 300 kW crawler bulldozer were taken as a research object, whose steady-state temperature field analysis and modeling were conducted and the relevant suggestions for improvement were put forward. The analysis results can provide reasonable parameters for the further structure research and development of viscoelastic suspensions.
