Abstract
A ‘Virtual Running Test Environment' has been in development, based on Hardware In the Loop Simulation (HILS) technology to emulate, in detail, railway vehicle motion on real tracks. The existing HILS system only reproduces the rigid body motion of a railway vehicle while running. In order to create a more realistic virtual running test environment, trials have been conducted to expand the frequency range of the HILS system to include and evaluate the elastic vibration of railway vehicle carbodies. This paper reports on frequency enhancement of the test equipment and about the construction of the numerical model including reproduction of elastic vibration.
