摘要:
根据构架在实际运行中的受力特点,提取4 种超常载荷工况对构架静强度进行分析,其最大节点von-Mises 应力为118.181 MPa,位于稳定轮与构架连接处,小于构架材料Q345A 的最大许用等效应力293 MPa。分析正常运行时利用FAMOS 采集的牵引曲线工况下构架测点动应力值,将其代入材料的Goodman 疲劳极限图中进行构架疲劳强度分析,测点的最大、最小应力值及应力幅值均在材料疲劳强度的许用范围内,表明构架的静强度和疲劳强度均满足设计和使用要求。
Abstract:
According to the mechanical characteristics of frame actual operations, four supernormal conditions were obtained and simulated for the static strength. The results showed that the maximum von-Mises stress was 118.181MPa, locating in the connection of stabilizing wheel and frame, which less than 293MPa, the allowable maximum stress of material Q345A. Furthermore, dynamic stress values of frame measuring points was analyzed, which measured by FAMOS in normal operation of traction curve condition. By substituting the value in Goodman fatigue limit diagram and analyzing fatigue strength, the maximum and minimum stress and stress amplitude of measurement points were proved within the range of allowable material fatigue strength, which showed that static strength and fatigue strength of the bogie frame met the requirements of design and operation.
