Abstract The aim of this study is to analyze the stiffness of finite line contact under elastohydrodynamic lubrication (EHL) with linear and nonlinear force approximations. The numerical solution of the finite line contact is compared with experimental results of optical interferometry. Four types of profiles are evaluated: non-profiled roller, crowned roller, dub-off profile and logarithmic profile. For each type of roller, the geometry values vary in order to identify the behavior of the reduced contact force parameters. The results of the force model showed good correspondence with the numerical solution of the EHL contact.

考虑线性和非线性力模型的弹性流体动力润滑下的有限线接触刚度

摘要 本研究的目的是使用线性和非线性力近似分析弹性流体动力润滑 (EHL) 下有限线接触的刚度。有限线接触的数值解与光学干涉测量的实验结果进行了比较。评估了四种类型的轮廓：非异形滚子、凸面滚子、复制轮廓和对数轮廓。对于每种类型的滚子，几何值会有所不同，以便识别减少的接触力参数的行为。力模型的结果与 EHL 接触的数值解显示出良好的对应关系。
