摘　　要：为探明快慢速共线运行160 km/h级市域快线中,曲线参数对行车舒适性、安全性的影响规律,为工程设计提供理论和技术支持,采用静态分析、舒适度试验和车-线动力学分析相结合的方法,研究与160 km/h级快线系统匹配的最小曲线半径标准.给出满足安全度和舒适性的最大超高建议值,用动力学分析法验证建议值的合理性;证明车体横向加速度是确定城轨线路欠、过超高最大值的控制因素,且过超高对旅客舒适度的影响与欠超高相当;建立车体横向加速度与欠超高的关系模型;基于所建立的关系模型,确定欠超高和过超高允许值;综合考虑最佳车-线动力学特性和工程技术条件,给出快慢速列车共线运行的160 km/h级市域快线最小曲线半径标准建议.研究可为规范标准的制定提供依据。This paper gives the maximum allowable cant meeting the requirements of safety and comfort and verifies its rationality using dynamic analysis method. It is proved that car body lateral acceleration is a control factor to establish allowable values of deficient cant and surplus cant in urban rail lines,and the impact on passenger comfort generated by surplus cant is similar to that caused by deficient cant. A relationship model between car body lateral acceleration and deficient cant is established. Based on the relational model,the allowable values of deficient cant and surplus cant are determined. Considering the best car-track dynamic characteristics and engineering technology conditions,the minimum curve radius for the shared 160 km/h urban rail transit for both fast and slow trains is proposed. The research may provide the basis for formulating specifications and standards.
