A Study on the Coupled Vibration of Train wheel and Rail Dynamic Chaacteristics of Train Wheel with the Stepped Thickness

차륜과 철로의 연성진동에 관한 연구

The research was conducted for the purpose of examining the dynamic characteristics of train wheel at the running state and preventing the vibrations of the high speed railway. The stress at the boundary surface of web and rim, .sigma./sub c/, was analyzed in consideration of the uniform In-plane compressive stress depending on the conditions of rolling and the rotation of train wheel. Then the equation of transverse vibration of the annular plate with the stepped thickness was analyzed by Rayleigh-Ritz's method.
