| 中文摘要: |
| 利用磁弹性这种新型的无损检测方法对高速客车转向架焊接构架组焊后的残余应力和构架在疲劳试验过程中的残余应力进行了试验研究，得到了构架残余应力随循环周次的变化规律 |
| 英文摘要: |
| The residual stresses caused by welding in bogie frames of high speed passenger car are measured by using magneto elastic method. The variations in the residual stresses during the fatigue test of the frames are also investigated. |
