Study on curving performance of railway bogies by using full-scale stand test

Abstract

Abstract High specific bogie rolling test facility that can simulate curving condition was developed in 1988. Until now, various kinds of experiments and tests were carried out on the facility. Those include the basic experiments of wheel/rail contact mechanism, such as creep characteristics, formation mechanism of rail corrugation, and improvement of curving performance by using friction modifier. The curving performance tests of newly developed bogies were carried out on this facility, and some of those have been already realized on commercial lines. The results of experiments and tests on this test facility are verified for agreement with the results of numerical simulations and train running tests on commercial lines.
