基于AMESim的有轨电车液压制动单元建模与分析

Modeling and analyze the trolley-bus hydraulic braking unit based on AMESim

基于低地板有轨电车液压制动原理,参考用于长春轻轨低地板车制动系统,运用AMESim仿真软件,建立拖车液压制动单元模型,仿真分析关键元件的性能和制动系统的制动过程,并讨论了蓄能器参数对制动缸压力动态性能的影响。仿真结果从理论上验证了制动单元的可靠性,也通过参数化动态分析为国产化液压制动系统的设计、改进提供了依据。

Build the hydraulic braking unit model to analyze the characteristic of the important cell and the braking process of braking system by using the AMESim simulation software based on the low- floor trolley- bus hydraulic braking principle after consulting the low- floor braking system used in light rail of Changchun. Then discuss the influence between the accumulator parameter and brake cylinder pressure dynamic performance. The simulation results verify the feasibility of braking unit,and provide the basis for the domestic hydraulic braking system design and its improvement through the parameter dynamic analysis.
