摘要:
为研究机车车辆轮轴接触面的应力值与过盈量之间的关系特征,应用基于弹性力学的传统接触应力计算式和有限元的计算方法进行了分析。根据采集的11 个车轴截面的应力值与对应的过盈值绘制出曲线图,并采用数值分析方法计算线性相关系数r。分析结果表明,车轴的轮轴配合面及其附近区域的计算应力值与过盈量之间都存在良好的线性相关性,且轮轴配合区域的应力值受过盈值上升的影响较大,车轴其他区域应力值所受的影响较小。
Abstract:
In order to research the relationship characteristic between the interference fit value and stress value of wheel-axle, the traditional contact stress formula based on the mechanics of elasticity and the finite element method was applied. Graphs according to the stress data of 11 picked axle sections and corresponding interference fit value was drawn out, and the linear correlation coefficient r by numerical analysis method was calculated. The analysis results showed that there was a good linear correlation between the calculated stress value and the interference fit value of wheet-axle, and the stress value of the wheel-axle mating area on the axle was influenced greatly and the other areas were less influenced by the interference fit value.
