摘要:
为简化轮轨接触切向计算,基于FASTSIM算法和TRIAL算法提出了一种新的非赫兹切向算法。考虑到FASTSIM算法中不真实的抛物线边界,提出的算法采用椭圆接触边界,显著提高了切应力的计算精度,解决了非赫兹接触条件下蠕滑力不饱和的问题。以CONTACT模型为参考,通过大量轮轨接触工况,验证了提出模型的计算精度、效率与稳健性。该模型可以被进一步应用于车辆-轨道动力学与轮轨损伤计算中。
Abstract:
To simplify the tangential calculation of wheel-rail contact,a new non-Hertzian tangential algorithm was proposed based on the FASTSIM and TRIAL algorithms. Considering the unrealistic parabolic boundary in the FASTSIM algorithm,the proposed algorithm adopted an elliptic contact boundary,significantly improving the computational accuracy of the shear stress and solving the non-saturation of creep force under non-Hertzian contact conditions. By using the CONTACT model as a reference and through numerous wheel-rail contact scenarios,the computational accuracy,efficiency,and robustness of the proposed model were validated. This model can be further applied in vehicle-track dynamics calculations and wheel-rail damage computations.
