摘要
以SS7E型电力机车轴箱拉杆为研究对象,为适应提速需要,在安装空间、接口不变的前提下,对老结构产品进行改进。刚度及疲劳试验结果表明:新结构完全满足主机厂纵向和横向刚度要求,具有更长的疲劳寿命。新结构保证了机车一系定位刚度,满足更高速度的运行。
The axle box pull rod of SS7E Electric locomotive was introduced. According to the requirement of speedup, the structure of old product was improved based on the same space envelope and interface dimension. The stiffness and fatigue test results indicated that new structure product could meet the stiffness requirement and had the longer fatigue life, the application results also showed that it could provide the proper primary suspension stiffness and meet high-speed requirement of locomotive.
