摘要
为研究高速动车组轴箱转臂定位节点的刚度演变,保障高速动车组安全、平稳、经济的运营,以CRH2型动车组轴箱转臂定位节点为研究对象,阐述轴箱转臂定位节点的结构组成、安装及刚度试验,探讨轴箱转臂定位节点在运营及疲劳试验前后的刚度演变过程。根据刚度演变情况进行安全性能分析,通过SIMPACK软件计算刚度变化前后,脱轨系数、轮轨横向力、轮轴横向力、磨耗系数的变化情况,并根据轴箱转臂定位节点的表面状态及刚度演变引起的动力学指标的变化,提出CRH2型动车组轴箱转臂定位节点在正常运营状态下最佳更换周期为5 a,为动车组检修及零部件更换提供参考。
To study the stiffness evolution of axle box arm positioning node of high-speed EMU and ensure the safe, stable and economic operation of high-speed EMU, taking the CRH2 type EMU axle box arm positioning node as the research object, the structure composition, installation and stiffness test of axle box rotating arm positioning node are expounded, and the evolution of stiffness before and after the operation reference and fatigue tests of axle box arm positioning node are discussed. The safety performance is analyzed based on the stiffness evolution, and the dynamic calculation is carried out by SIMPACK software. The variation of derailment coefficient, wheel-rail lateral force, wheel-axle lateral force and wear coefficient is obtained after the stiffness change. The optimal replacement period of the CRH2 EMU axle box turning arm positioning node is 5 years under normal operation, which provides reference for EMU maintenance and spare parts replacement.
