摘要
以ＨｅｌｌｉｎｇｅｒＲｅｉｓｓｎｅｒ 变分原理为基础，应用摄动拉格朗日技术，将轮轨视为有限弹性体，推导出轮轨稳态滚动接触的ＨｅｌｌｉｎｇｅｒＲｅｉｓｓｎｅｒ 变分原理。
Based on the variational principle of Hellinger Reissner and using the perturbed Lagrange technology, the variational principle of Hellinger Reissner for wheel rail steady rolling contact is discussed with wheel and rail being regarded as finite elastic bodies. It provides theoretical and computational bases for more accurate numerical computation of the contact fatigue of wheel and rail.
