The bogie, when rotated relative to the car body develops the rotational resistance factor. This will be confirmed by testing under different loading conditions and air springs inflated and deflated in all conditions. Under the most extreme roll, EMU (Electrical Multiple Unit) shall not violate the kinematics envelope. The present article will utilize the multi-body program, MEDYNA, to study the rotational resistance factor in bogie design, as applied to both inflated and deflated air springs. Meanwhile the unique characteristics of a bogie is examined and confirmed through rotating resistance test.
