基于网格辅助技术的车轴强度计算与可视化方法
The Calculation and Visualization Method of the Rail Vehicle’s Axle Strength Based on Grid Assisted Technology

为改善基于欧洲标准计算车轴强度方法的不足，采用有限元网格辅助技术，结合材料力学的基本理论，通过编制程序对车轴的全域应力与材料利用度展开计算，并将结果可视化，可视化结果以线图与云图的形式呈现。这种方法可以实现对车轴准确的强度评估，为车轴结构强度的设计提供参考，具有较高的实用价值。
In order to improve the deficiency of the axle strength calculation method based on The European standard, the finite element mesh-assisted technology and the basic theory of material mechanics were adopted to calculate the axle’s global stress and degree of material utilization through pro-gramming, and the visualized results were presented in the form of line graph and cloud map. This method can be used to accurately evaluate the strength of axle and provide reference for the design of axle structure strength which has great practical value.
