Prediction of the response of a train of 5 Mk 3 coaches to the lateral pressure fluctuations which occur when two HST units pass at 125 mph (VDYN 26 (ISSUE 2))

When two HST vehicles pass in opposite directions at high speed they subject one another to lateral pressure fluctuations. These apply lateral forces to the vehicles, which in turn generate lateral and yaw displacements across the suspension. An ACSL program (see reference 1) has been developed which simulates this...
