ABSTRACT

The electromagnetic damper (EMD) is an oil-less shock absorber which absorbs vibration by converting vibration energy to electric energy by an electric motor. In the previous study, the authors proposed a coupling method of four EMDs with an electric circuit which enables the damping characteristics of bouncing, rolling, and pitching motion of a vehicle to be tuned independently. In this study, the authors focus on hardware-in-the-loop simulation (HILS) to verify the effectiveness and validity of the coupled EMD. The experimental setup which is composed of coupled motors is built for the hardware of HILS system and vehicle dynamics simulations with four motors are carried out. The results show that the proposed coupling method is valid and effective.
