| 摘 要： | 本文探讨低动力作用货车转向架的原理及其动力性能的计算和评估方法。首先定义9项指标,作为衡量车辆对轨道动力作用的标准。然后研究这些指标的诸因素。在此基础上总结出实现低动力作用的基本途径。本文还应用这些研究成果,提出4种低动力作用货车转向架的设计方案,并通过数值计算,同国内、外主型货车转向架对比,从而论证其在我国铁路采用的可行性。

| Abstract: | The theory and the method of dynamical analysis of low track force freight bogie are studied in this paper. Nine indices are defined for track force evaluation, and then factors effecting on these indices are systematically investigated. Based on the investigation, main measures of reducing the track forces are summarized. As an application, four designs of low track force bogie are recommended and the track force indices are calculated in comparison with other types of freight bogie, verifying the feasibility of the designs. |
