低地板有轨电车液压制动系统及制动力管理策略研究

Management Strategy for Hydraulic Braking System and Braking Force of Low-floor Tram

介绍了所研制的低地板有轨电车液压制动系统的组成及工作原理。重点论述了电制动力与液压制动力转换阶段制动冲击率的控制方法,以及正常工况下和故障模式下的制动力管理策略。提出了一种故障模式下新的液压制动力管理策略,可有效降低车轮擦伤风险。

The composition and working principle of the developed hydraulic braking system are introduced.By focusing on the control method of braking impact rate during the braking process of electrodynamic breaking and hydraulic braking,the braking management strategies under normal working condition and fault mode are elaborated.On this basis,a new hydraulic braking force under the fault mode management strategy is put forward,in order to effectively reduce the risk of wheel scratch.
