摘要

研究了带径向机构的铰接式单轴转向架独立轮对导向特点。理论上分析了传统轮对和独立轮对的导向原理，在SIMPACK 中建立了5 节编组的Talgo 列车动力学模型。结合Talgo 列车三角拖动式结构研究了独立轮对的对中性能。对比了带径向机构的独立轮对、不带径向机构的独立轮对以及传统轮对在曲线通过时的轮对冲角、磨耗指数、脱轨系数和车轮横向力，指出径向机构可以有效降低轮对冲角和车轮磨耗, 并分析了不同轮对脱轨系数差异较大的原因。

Abstract

The steering characteristic of articulated single-axle bogie independent wheelset with radial mechanism was studied. Thesteering principle of traditional wheelset and independent wheelset was analyzed theoretically, and the dynamic model of 5-carbody Talgotrain was established in SIMPACK. Reset capability of lateral displacement of wheelset was studied from aspect of triangle frame of Talgotrain. The angle of attack, wear index, derailment coefficient, wheel lateral force among the independent wheelset with radial mechanism,without radial mechanism and traditional wheelset were compared, and it was pointed out that the radial mechanism could reduce the angleof attack and the wear index effectively, as well as the reason resulting in difference of derailment coefficient was studied.
