摘要: 合理的轮轨型面匹配能改善轮缘磨耗。在调研国内外经典型面的基础上,设计主踏面由6段圆弧组成的基准型面。提出低轮缘磨耗地铁车轮设计方法,该方法由车辆动力学模型、车轮型面生成程序、多目标优化数学模型、径向基函数代理模型和NSGA-II优化算法组成。以DIN5573型面作为对比型面,从轮轨静态接触特性、车辆动力学性能和车轮磨耗演变3个方面对优化得到的型面进行检验。结果表明,优化型面很好地兼顾了运行稳定性和曲线通过性能;优化型面的非线性临界速度满足运行需求,运行平稳性与DIN5573型面相似,曲线通过性能普遍优于DIN5573型面;10万km磨耗预测下,优化型面的轮缘厚度损失量降低78.6%,轮缘磨耗量降低61.8%。

Abstract: Proper wheel-rail profile matching can improve wheel flange wear. Based on the investigation of several typical wheel profiles at home and abroad, a datum profile consisting of six arcs is presented. A design method of low flange wear metro wheel is proposed, which is composed of vehicle dynamics model, wheel profile generation module, multi-objective optimization mathematical model, radial basis function surrogate model, and NSGA-II optimization algorithm. Taking the DIN5573 profile as the contrast profile, the optimized profile is verified by wheel-rail static contact characteristics, vehicle dynamic performance and wheel wear evolution. The results show that the optimized profile can give good consideration to both the running stability and curving performance. The nonlinear critical speed of the optimized profile meets the operating requirements, and its ride comfort is basically the same as that of the DIN5573 profile. The curving performance of the optimized wheel profile is better than that of the DIN5573 profile. In addition, the wear evolution performance of the two wheel profiles is compared at 100 000 km mileage. Compared with the DIN5573 profile, the flange thickness loss of the optimized wheel profile decreases by 78.6%, and its flange wear decreases by 61.8%.

Key words: multi-objective optimization, wheel profile design, wheel wear, arc parameter, vehicle dynamics, surrogate model
