Stress-deformation-temperature behavior of a rolling segmented constrained layer damped bogie wheel

Stress-deformation-temperature characteristic of a segmented constrained layer damped (SCLD) bogie wheel used in crawler construction vehicles is analyzed in this paper. The SCLD bogie wheel mainly consists of three layers, namely the base, constrained and viscoelastic layer. The rubber in the viscoelastic layer is considered to be isotropic, incompressible and hyper-elastic, and its mechanical properties are assumed not to be dependent on temperature. Some important characteristics of the rolling SCLD bogie wheel are obtained based on the FE computation and analysis, such as the maximum stress and strain, the heat easily accumulated region, and so on. Suggestions for improving the performance of SCLD bogie wheel are put forward. The rationality of the simplified FE model is verified through the corresponding deformation test. At the same time, the related measurements are performed in order to obtain the performance of the SCLD bogie wheel. The research result is available to the further development of bogie wheel for crawler construction vehicles.
