Segmented Constraining Layer Damping Treatments for Bogie Wheel

Abstract

A new type of composite bogie wheel is introduced in this paper. To understand its mechanical characteristics, a crawler bulldozer, operated under different working conditions, was taken as an application example, and a numerical model of the new composite bogie wheel has been established and analyzed. The analysis result shows that the new composite bogie wheel can meet the strength requirement. To verify finite-element (FE) result, an electro-hydraulic servo and program-controlled testing machine were used to measure the deformation of the bogie wheel specimen. The obtained experimental result indicates a good agreement with result from FE analysis. Finally, a contrast experiment was conducted in a practical crawler bulldozer, and the result shows that reductions of the vibration level may reach 5 dB to more than 9dB by the use of the new composite bogie wheel. The result in this article is helpful to the further development of high-performance bogie wheels used in crawler construction vehicles.
