THE ELASTIC FACTOR OF RAIL VEHICLE WHEELS

Richard de Beer

Open publisher page 0 citations

Abstract

There have been constant efforts to increase the elasticity of rail vehicle wheels, in other words the elastic factor to be applied. This is determined by calculating the maximum dynamic vertical stress borne by the wheel when passing over a rail joint in relation to the radial elastic factor. The authors, who use a system of ordinary differential equations to solve this problem, with the help of an analog computer, obtain a radial elastic factor for impact reduction.
