Hunting stability is one of the most essential characteristics for high speed trains, and it has been investigated by roller rig testing at testing bench and numerical simulation. Those ways have their own problems in their accuracy, cost and flexibility. We propose a new approach, Hardware-In-the-Loop Simulation (HILS), to test hunting stability for railway vehicles. HILS is a kind of simulation that uses some actual devices. It enables us to increase simulation accuracy, keeping its cost and flexibility reasonably. In this paper, we demonstrated hunting stability tests by HILS that shows the test works properly. Furthermore, we also demonstrated simulation studies to identify excitation devices responsiveness for quantitative evaluation of hunting stability.
