本文提出了一种多尺度建模方法,在轮轨接触表面粗糙度不能忽略的情况下,利用压力测量薄膜再现轮轨接触面积的测量结果。借助基于扫描表面数据的有限元方法研究了薄膜与测试体之间的微观接触行为,并随后在再现接触面积测量过程的宏观模型中实施。模拟结果与实验测量结果的一致性验证了该建模方法的有效性。压力测量膜对粗糙度变化的响应与主导接触机制是一致的。
This article presents a multiscale modeling approach for reproducing the measurement of the wheel–rail contact area using pressure measurement film when the roughness of the mating surfaces cannot be neglected. The microscopic contact behavior between the film and test bodies was investigated with the aid of the finite element method based on scanned surface data and was later implemented in a macroscopic model that reproduced the contact area measurement procedure. The validity of the modeling technique was confirmed by the consistency between simulated results and experimental measurements. It was also demonstrated that the response of the pressure measurement film to roughness variations is consistent with the governing contact mechanics.
