and 6. The results show clearly that the varying crosswindspeed has little impact on the sharp magnitude of aerodynamic forces, but it is noticeable from Table 6 that themagnitudes of aerodynamic load, particularly for the liftforce and rolling moment, remain an approximately linear dependence with the squared train speed. For the sidefore, it is worth remarking that the increasing train speedimproves the sudden change but it is not a linear functionof the squared train speed. The main reason for this phenomenon may be that the moving train can only affectthe pressure distribution on the bridge deck rather thanthat of side surface.
