Study on Running Resistance of Straddle-Type Monorail Car

为了研究跨座式单轨车辆运行中力与加速度的相互关系,即研究单轨车辆的运动方程,基于汽车行驶阻力和列车运行阻力两种计算模式相结合的研究方法,对跨座式单轨车辆运行时的主要阻力进行探究.推导出了跨座式单轨车辆在不同线路中运行阻力的理论公式,基于SIMPACK建立了曲线附件阻力的理论公式,提出了加速附加阻力公式.

Deducing motion equation of straddle-type monorail car is one of major tasks researched by traction calculation of monorail car. While deducing motion equation of monorail car is based on determination of running resistance of monorail car. As to straddle-type monorail car, the rolling resistance of running wheel plays the key role in the whole running resistance （without considering bearing resistance）, which is different from the common rail train. Meanwhile, unlike automobile, monorail car involves curve additional resistance and tunnel additional resistance. Therefore, this paper study on running resistance of straddle-type monorail car, is mainly based on such researching methods combined by two types of calculating models as automobile running resistance and monorail car running resistance, theoretical formula about curve additional resistance of straddletype monorail car has been derived and running resistance of monorail car has been drawn finally.
