运用条形切割法 ,对桥梁、建筑等结构设计中常用的厚板焊接箱形杆件等构件的残余应力分布进行实例测试 ,通过对测试数据的分析整理 ,得出厚板焊接箱形杆件和 T形杆件截面纵向残余应力分布情况 ,为进一步总结焊接结构的残余应力分布规律提供了基础 .
The strip cutting method is used to test the residual stress distribution of thick-walled welded box-shaped bars and other components commonly used in the structural design of bridges and buildings. By analyzing the test data, the thick-plate welded box-shaped bars And the distribution of longitudinal residual stress in the T-bar section provide the basis for further summarizing the residual stress distribution of the welded structure.
