摘　　要：文章介绍了铰接式转向架的结构特点,建立了两车体三转向架的车辆动力学模型,参考GB/T 5599—1985标准,研究了铰接式转向架车辆在正常线路、侧风和空气弹簧失效工况下的平稳性和曲线通过性等动力学性能。经分析得到:正常线路工况与侧向风工况下,列车动力学响应均能满足要求;空气弹簧失效工况下,列车平稳性指数过大,为保证列车安全运行,需对车辆限速。The paper presents the structural characteristics of the articulated bogie,and establishes the vehicle dynamics model with two car bodies and three bogies.Refer to GB/T 5599—1985,the dynamic properties such as stability and curve passing of the articulated bogie vehicle are studied under the conditions of normal line,crosswind and air spring failure.The results show that the train dynamics response can meet the requirements under normal line condition and crosswind condition;the train stability coefficient is too large under air spring failure condition,and the train speed should be limited to ensure the stable operation.
