胶轮导轨电车特殊工况运行平稳性研究

Running Stability Analysis of Rubber-tired Tram in Special Condition

胶轮有轨电车在设计运营成本、爬坡能力、曲线通过半径和运行噪声等方面较传统城市轨道交通有很大优势。针对胶轮导轨电车在运营过程中,可能会遇上冰雪天气,车轮爆胎、空簧失效、减振器失效等特殊工况,通过SIMPACK多体系统动力学软件,对胶轮导轨电车在特殊工况下运营进行了动力学分析。分析结果表明:在特殊运营工况下通过降低运行速度等方法可以满足运行平稳性要求。

Compared with the traditional urban rail transik the rubber-tired tram has great advantage in the design and operating cost, climbing ability, curve negotiation and operating noise. During the operation, lots of the accidents that the puncture wheel, the failure air spring and the defective shock absorber, would happen in the ice and snow weather, Using the SIMPACK multi-body system dynamics software, the dynamic performance of the rubber-tired tram in special condition was analyzed. The analysis results showed that lowering the operating speeds could meet the running stability of the rubber-tired tram in special condition.
