摘要:

液压防折弯系统是单车型低地板轻轨车上用以提高列车运行平稳性、稳定性和曲线通过性能的重要部件，具有防折弯和横向减振两大功能.通过对防折弯系统原理进行分析，建立了影响其横向减振功能的阻尼数学模型，并仿真分析了缓冲阀门组中的节流阀和限压阀对阻尼特性的影响.阻尼特性的仿真曲线与试验曲线吻合较好，证明了阻尼模型的正确性.

关键词:低地板轻轨车; 防折弯系统; 阻尼特性; 数学模型

Abstract:

The hydraulic antikink system is an important component equipped in lowfloor trams to improve the riding quality, stability and curving behavior of the vehicles. The system has two functions in antikink and lateral damping. A mathematical model for damping properties was established based on the operating mechanisms of the system. Furthermore, the influence of throttle valve and pressure limiting valve on the damping characteristics of the system was investigated by simulation. The calculating curve of the damping characteristics coincides with the experimental curve, which proves the correctness of the damping mathematical model.

Key words:lowfloor tram; antikink system; damping characteristics; mathematical model
