摘　　要：钢轨打磨能有效抑制波磨的发展,目前的打磨限值制定标准主要以车辆运行平稳性和行车安全性为依据,对影响环境线路的轮轨滚动噪声重视不足。为了获取服役条件下轮轨滚动噪声约束的地铁波磨打磨限值,根据对某地铁线路噪声段波磨情况的调查,建立了地铁波磨打磨限值综合评估模型。模型中将连续谐波模拟钢轨波磨作为系统输入,根据车辆-轨道耦合动力学理论以及轮轨接触关系确定轮轨动作用力和轮轨表面粗糙度之间的关系,分析获取了车辆-轨道耦合系统的振动响应和轮轨滚动噪声,指出了轮轨动作用力、轮重减载率和轮轨滚动噪声声压级3个指标对地铁线路钢轨波磨打磨限值的影响,进而形成了融合轮轨滚动噪声的地铁波磨打磨限值评估方法。结果表明:考虑轮轨滚动噪声影响的钢轨波磨打磨限值评估,不仅满足车辆运行平稳性和行车安全性的要求,而且保证地铁沿线噪声处于合理范围;基于轮轨滚动噪声对钢轨波磨最为敏感的特性,综合评估地铁波磨打磨限值,提高了载重变化时的车辆运行平稳性。Rail grinding can effectively restrain the development of rail corrugation.At present,the formulation standard of grinding limit is mainly based on vehicle running stability and driving safety,and the negative impact of wheel-rail rolling noise is paid insufficient attention to the environment in the current standard of grinding limit.To obtain the limit value of metro rail corrugation grinding under the constraint of wheel-rail rolling noise and service conditions,a comprehensive evaluation model for rail corrugation grinding limit value is established.In the model,the continuous harmonic simulation rail corrugation is taken as the system input.According to the vehicle-track coupling dynamics,the relationship between wheel-rail action force and wheel-rail surface roughness is determined.The vibration response and wheel rail rolling noise of vehicle track coupling system are analyzed and obtained,and effects of critical parameters are pointed out.Then,a prediction method of rail corrugation grinding limit for metro based on wheel-rail rolling noise is proposed.Results show that the prediction of rail corrugation grinding limit considering the influence of wheel-rail rolling noise not only meets the requirements of vehicle running stability and traffic safety,but also ensures that the noise along the metro is in a reasonable range.Based on the characteristics of wheel-rail rolling noise that are most sensitive to rail corrugation,of metro corrugation grinding limits are comprehensively evaluated and the vehicle running stability when the load changes is improved.
