On the Acoustic/dynamic Characteristics of the Resilient Wheel : Part 2 ; a Theoretical Analysis on the Radial Dynamic Characteristics

Abstract

To suppress the wheel/rail roar noise effectively by use of a resilient wheel, the detailed dynamic characteristics of the wheel must be clarified. In this paper, the resilient wheel is regarded as a ring with T-section supported discretely on a rigid circular cylinder, a method of analysis on its radial dynamic characteristics is proposed and the accuracy of analysis is improved by consideration of shearing deformation and rotatory inertia.
