摘要:
针对轨道参数对机车车轮磨耗的影响问题, 以D20E 型内燃机车为例, 借助SIMPACK 软件建立了机车动力学模型。提出根据机车动力学模型、FASTSIM 算法与Zobory 磨耗预测模型为一体的机车车轮磨耗预测模型,并编制了相应计算程序。利用该模型,分析轨道主要参数对机车车轮磨耗的影响。结果表明:车轮磨耗深度随曲线半径增大而迅速减小;随着轨距的增加,车轮磨耗深度明显降低,磨耗分布范围有所增加;五级谱、六级谱下车轮圆周磨耗深度较四级谱下的结果低;线路等级越差,车轮磨耗分布范围越宽;轨底坡的适当减小可使得车轮磨耗有一定降低;适当减小摩擦系数对于降低轮轨磨耗是有利的。
Abstract:
Aiming at the effect of railway parameters on wheel wear of locomotive, D20E type diesel locomotive dynamics model was built by SIMPACK software. A model combined locomotive dynamics, FASTSIM algorithm and Zobory profile wear model was built, and wheel tread wear simulation program was developed. The effect of railway parametes on wheel wear was analyzed. The results indicated that, the wheel wear depth decreased rapidly with the increase of curve radius; the wear depth obviously decreased and the wear distribution range increased with the increase of rail gauge; the wheel wear depth in America five grade railway, America six grade railway was less than that in America four grade railway; the wear distribution range increased with the worse grade railway; the rail cant was reduced properly, wheel wear would be decreased; decreasing properly the friction coefficient could favorably reduce wheel wear.
