摘　　要：本文根据8辆编组A型地铁列车的缓冲器吸能技术要求对车钩缓冲器进行了选型分析。对地铁列车常用的胶泥缓冲器、气液缓冲器、EFG3橡胶缓冲器的吸能特性、蠕变特性、重量、可维修性、适用性等各项性能参数进行了对比分析,为配置车钩方案提供了依据。根据8辆编组A型地铁列车的吸能设计要求,配置了胶泥缓冲器、气液缓冲器、EFG3橡胶缓冲器及吸能装置的车钩方案。使用专用动力学仿真程序对三种车钩配置方案的有效性和可靠性进行了纵向动力学计算仿真和坡道救援计算仿真分析。结合仿真结果,对8辆编组A型地铁列车的缓冲器选型提出了建议。According to the energy absorption technology requirements of buffers of 8-car A-type metro trains,this paper analyzes the selection of coupler buffers,and compares and analyzes performance parameters such as energy absorption characteristics,creep characteristics,weight,maintainability and applicability of elastomer buffers,gas-liquid buffers and EFG3 rubber buffers,which are commonly used in metro trains,thus providing a basis for the coupler scheme configuration.Based on the energy-absorbing design requirements of 8-car A-type metro trains,this paper designs coupler schemes for elastomer buffers,gas-hydraulic buffers,EFG3 rubber buffers and energy-absorbing devices.Longitudinal dynamics calculation simulation and ramp rescue calculation simulation analysis of the effectiveness and reliability of the three coupler configuration schemes were carried out using a special dynamics simulation program.Combined with the simulation results,this paper makes recommendations on the selection of buffers for the 8-car A-type metro trains.
