为了评估在纵向力作用下重载机车的曲线通过性能,结合澳大利亚标准以及美国工作手册中提出以车轮抬升率为评估指标的方法进行计算分析。在原有标准转向架横向力计算的基础上,推导出不同牵引机车数量、考虑列车离心力作用情况下转向架横向力的计算公式。同时运用公式从不同机车编组方式、设计结构参数以及离心力3个方面对机车的曲线通过性能的影响进行了分析,并以某出口机车为例验证了两列机车牵引方式车轮抬升率小于单列机车牵引方式、参数钩间距对车轮抬升率影响较明显的结论,为重载机车的运行与发展提供了理论计算参考以及参数设计意见。
In order to evaluate the curve passing performance of heavy-duty locomotives under the longitudinal force, the calculation and analysis based on the Australian standards and the U.S. work manual are proposed to evaluate the wheel lift rate. Based on the calculation of the lateral force of the original standard bogie, the formula for calculating the lateral force of the bogie with different numbers of traction locomotives and the centrifugal force of the train is deduced. At the same time, the formula is used to analyze the curve passing performance of the locomotive from three aspects: the grouping mode of different locomotives, the design parameters of the structure and the centrifugal force. The example of a locomotive at an exit verifies that the traction rates of two locomotives are less than that of single locomotive traction Method and parameter hook spacing have obvious influence on wheel uplift rate, and provide theoretic calculation reference and parameter design opinion for the operation and development of heavy-duty locomotive.
