Buffer property analysis of spaced-damping layer bogie wheel

Based on the current situation of poor vibration damping performance of traditional bogie wheel, a kind of spaced–damping layer structure was applied to the bogie wheel to improve its vibration damping performance. A crawler tractor was taken as an application example, the vibration damping models for the whole vehicle and single bogie wheel were established, and the amplitude-frequency characteristic response functions of bogie wheels were deduced. With the performance simulation and comparative analysis between the traditional and improved bogie wheels performed by Matlab, the results show that the vibration suffered by the crawler tractor can be buffered effectively by the new bogie wheels. With strength analysis of the improved bogie wheels carried out by ANSYS, the results show their strength can meet the operating requirements under the different working conditions of the crawler tractor.
