摘　　要：在城市轨道交通线路中,曲线占比较高,且曲线半径相对较小。准确评估曲线健康状态,对合理利用维修资源、优化安排维修计划具有重要意义。提出了一种新的曲线健康评定模型,利用车体的振动与噪声响应检测数据,构建状态评定指标体系,确定曲线健康指数。该评定模型可实现曲线健康状态的实时性准确评定。通过北京地铁1号线的实际检测数据验证了该模型的有效性。计算结果表明:曲线健康指数可用以全面评定曲线健康状态,能够满足现场管理需求。In urban rail transit lines,curves have relatively high proportion,and the radius is relatively small.Accurate assessment of curve health condition is of great significance to allocating maintenance resources reasonably and optimizing maintenance scheduling.A new curve health evaluation model is proposed.The measurement data of vehicle body vibration and noise response is used to establish a condition evaluation index system,and curve health index(CHI)is determined.Accurate real-time assessment of curve health condition can be obtained from evaluation model.The effectiveness of the model is verified by the actual measurement data accumulated in Beijing Metro Line 1.Calculation results show that CHI can be used for comprehensive evaluation of curve health condition and can meet on-site metro management requirements.
