车辆定距-
随着车辆定距的增大，运行速度的提高以及由线路因素和车体因素引起的激扰频域的加宽，导致车辆振动加速度增大，弹性振动的幅度加剧，从而影响到车体的运行性能。
With the vehicle spacing increasing , the speed improving and the widening of the frequency domain which were caused by rail and carbody factors , the vibrating acceleration increased , and then encouraged strenuous elastic vibration .
