摘要: 为研究不同轮轨非赫兹滚动接触算法对道岔轮轨滚动接触行为的影响,以转辙器部件为例,建立能够考虑尖轨和基本轨相对运动的轮轨滚动接触模型,对比分析Kalker三维滚动接触理论、Kik-Piotrowski、Ayasse-Chollet和Sichani四种非赫兹滚动接触算法在求解轮轨法向和切向接触行为时的计算精度和效率。结果表明,与Kalker三维滚动接触理论相比,采用Sichani方法在求解道岔轮轨法向和切向接触行为时的计算精度最高,最大计算误差均在10%以内,而由于条带理论自身的缺陷,在轮轨纯自旋蠕滑情况下,Sichani方法求解切向接触应力最大值的计算精度有所下降,计算误差为30%左右;采用Kik-Piotrowski方法的计算效率最高,Ayasse-Chollet和Sichani方法次之,Kalker三维方法所需的计算时间最长。综合计算精度和效率,Sichani方法是求解铁路道岔轮轨滚动接触行为较为合理的接触模型。

Abstract: In order to investigate the effect of different wheel-rail non-hertzian rolling contact approaches on wheel-rail rolling contact behavior in railway turnout, a wheel-rail rolling contact model taking into account the relative motion of stock/switch rails is built which taking a switch panel of railway turnout as the example, and the computational accuracy and efficiency of wheel-rail normal and tangential rolling contact behavior by Kalker three-dimensional rolling contact theory, Kik-Piotrowski, Ayasse-Chollet and Sichani method are calculated and compared. The results showed that, compared with Kalker three-dimensional theory, the computational accuracy of Sichani method is highest when calculating the wheel-rail normal and tangential rolling contact behavior in switch panel of railway turnout, and the maximum calculation error is within 10%. The computational accuracy of Sichani method is reduced when solving the maximum value of tangential contact stress under the case of pure spin, and the calculation error is about 30%. The computational efficiency of Kik-Piotrowski method is the highest, Ayasse-Chollet and Sichani method take the second place, and the Kalker three-dimensional theory takes the longest time. Combined with the computational accuracy and efficiency, Sichani method is the more reasonable method to simulate the wheel-rail rolling contact behavior in railway turnout.

Key words: railway turnout, non-hertzian, rolling contact, normal, tangential, relative motion of stock/switch rails
