摘要
This work shows the method developed to solve the wheel-rail contact problem via a look-up table with a three-dimensional elastic model. This method enables the introduction of the two contact-point effect on vehicle movement using three-dimensional analysis of surfaces, including the influence of the angle of attack. This work presents several dynamic simulations and studies the impact that the introduction of the two contact points on three dimensions has on wear indexes and derailment risk against traditional bi-diniensional analysis. Furthermore, it studies advantages and disadvantages of using a look-up table against an on-line resolution of the problem.
