跨座式单轨车曲线通过性能评价指标研究

跨座式单轨车因其结构与传统的铁道车辆存在一定的差异,导致传统铁道车辆动力学性能的评价标准不再完全适用。本文借鉴《铁道车辆动力学性能评定和试验鉴定规范》(GB 5599—1985),根据跨座式单轨车的固有特点及其实际运用经验,提出以导向轮导向力、转向架导向力矩、车体浮心高度、走行轮轮重减载率、走行轮胎侧偏角以及走行轮胎最大垂向作用力等评价指标来对跨座式单轨车的曲线通过性能进行评价,并对各个评价指标进行了详细的分析研究。

Research on evaluation indexes of the curve negotiation performance of a straddle type monorail car

Since the structure has some differences between the straddle type monorail car and the traditional rolling stock,the dynamic performance evaluation criterion of the traditional rolling stock does not absolutely adapt to the straddle type monorail car.In this paper,drawing on the experience of "Railway vehicles–Specification for evaluation dynamic performance and accreditation test"(GB 5599—1985),and according to the immanent trait and practice experience of the straddle type monorail car,the evaluation indexes such as the guiding force of the guiding tyre,the guiding moment of the bogie,the height of the car body's centre of displacement,the rate of wheel load reduction of running tyre,the slip angle of running tyre,the maximal vertical force of running tyre,and so on,are put forward,which could be used to evaluate the curve negotiation performance of the straddle type monorail car,and each evaluation index is analyzed in great detail.
