摘要
在轨道交通装备安全轻量化目标的指导下,使用轻量化材料是轨道交通车辆轻量化的关键技术之一。钛合金因具有密度小、比强度高、可焊性好、耐腐蚀性好等特点,已受到轨道交通行业的重点关注。该文综述钛合金在轨道交通车辆转向架构架、制动夹钳、车钩、牵引拉杆及轮对提吊等零部件的应用研究现状,并提出钛合金在轨道交通装备上应用需解决的问题及建议。
Under the guidance of the safety lightweight goal of rail transit equipment,the use of lightweight materials is one of the key technologies for the lightweight of rail transit vehicles.Titanium alloy has been the focus of the rail transit industry because of its low density,high specific strength,good weldability,good corrosion resistance and so on.This paper summarizes the application and research status of titanium alloy in rail transit vehicle bogie frame,brake clamp,coupler,traction rod,wheelset lifting and other parts,and points out some problems and puts forward relevant suggestions for the application of titanium alloy in rail transit equipment.
