Measurement of wheel–rail contact forces is very important, but it is not executed so often because of its difficulties. A new measuring method introduced in this paper can measure such contact forces without special wheelsets equipped with strain gauges and slip rings or telemeters. In this method the lateral contact force is measured from the lateral distortion of wheel measured directly by several...
In very sharp curved tracks where the efficient difference of rolling radius between inside/outside wheels is hard to obtain by the bogie, various ill-suited phenomena, such as rail corrugation, squeal noise, derailment and etc., are occurring. The purpose of this study is to avoid these phenomena. The effect of friction modifier on the improvement of bogie curving performance has been systematically...
