摘　　要：针对高速列车转向架轻量化问题,采用APDL语言建立某型高速转向架焊接构架的参数化优化设计模型,以高速转向架焊接构架的质量为目标函数,以Goodman疲劳极限线图作为约束条件,对构架结构几何形状进行优化设计,结果表明:优化后构架的质量减少了11.9%,构架应力分布更趋于均匀,减少了应力集中的现象,构架强度满足JISE4207—2004标准的设计要求。To solve the lightweight problem with high speed train bogie, the parametric optimized design model of a welded bo- gie frame high-speed train was established by the APDL language. Taken the mass of welded bogie frame of high-speed train as object function, and the Goodman fatigue limit graph as restrictive condi- tions, the geometric shape of the bogie was optimized. The results show that after optimization the quality of bogie was decreased by 11.9%, the stresses were distributed more evenly and the stress concentration was reduced, structure strength is in compliance with the design requirements of JIS FA207-2004 standard.
