介绍导纳型机电类比的原理、参数对应关系,以及对应的类比电路图的绘制方法。通过该类比方法绘制出了轨道车辆垂向振动的类比电路图,应用相应电路分析理论,定量分析车辆一系垂向振动速度传递特性,得出减振所需要满足的条件。分析结果表明,应用机电类比法分析轨道车辆振动特性可以极大地简化分析过程。

The principle and parameter corresponding relation and the method of drawing analogy circuit are presented in this paper. The analogy circuit of rolling stock vertical vibration is constructed by this analogy method. The vertical vibration velocity transmission characteristic of the vehicle＇ s primary suspension is quantitatively analyzed by using the corresponding theory of circuit analysis, and the conditions for vibration reduction are gained. The results show that electro-mechanical analogy method can be applied in the vibration characteristic analysis of rolling stock and simplify the analyzing process dramatically.
