摘要:
为分析高速铁路道岔动力学响应，本文以18号可动心轨道岔（客专（07）009）为研究对象，运用多体动力学软件UM建立高速动车组模型和18号道岔模型，分析列车通过道岔时的轮轨力、舒适性指标和安全性指标，研究结果表明，各项动力学指标均处于舒适度限值以内，满足安全性要求。并对高速道岔设计和养护维修中，需要结合动力学仿真考虑的不平顺问题、轮轨关系问题和轨道刚度问题等进行了探讨，提出了指导性建议。
Abstract:
In order to analyze the kinetic response of high-speed railway turnout, this paper takes No.18 movable frog turnout (turnout (07)009 for passenger dedicated line) as the subject, establishes the high-speed EMU model and No.18 turnout model by using multi-body dynamics software UM to analyze the wheel-rail force, comfort index, and safety index when the train passes through the turnout. The results show that all the kinetic indexes are within the comfort limit and meet the safety requirements. Then, this paper discusses the irregularity of rail, wheel-rail relationship, and track stiffness that need to be considered in the design and maintenance of high-speed railway turnout, and puts forward some guiding suggestions.
