很多年来设計师对于車辆制造中消除綫路激扰所引起的共振的要点已經有所了解,但是随着列車速度的提高,要完全滿足这个要求是很困难的。在一般的速度下,可以将走行装置的固有頻率設計得足够。使車辆能在低于共振速度的区域內运行,但是在高速度时要达到这个要求是比較困难的,特別在横向平面內,即使将車輪踏面錐度从1/20减少到1/40,增加轉向架固定軸臣等也不能完全消除蛇行运动引起的强迫振动頻率。 For many years designers have gained an understanding of the main points of resonance mitigation caused by line disturbances in vehicle manufacture, but as the speed of the train increases, it is difficult to fully meet this requirement. At normal speeds, the natural frequencies of the running gear can be designed to be sufficient. So that the vehicle can operate at an area below the resonance speed, but it is more difficult to achieve this requirement at high speeds, especially in the transverse plane, even if the wheel tread taper is reduced from 1/20 to 1/40 The bogie fixed shaft and so on also can not completely eliminate the forced vibration frequency caused by the meandering motion.
