摘要
为顺应液压支架大型化方向发展的需要,相关结构件必然会越来越厚,对焊接工艺提出了更高的要求。Q550高强度结构钢是用来制作液压支架结构件的常用材料,以该材料为例研究了厚板多道次焊接过程中的温度场和应力场、焊接结束后的残余应力分布情况。将仿真研究结果与实验结果进行对比,发现两者之间吻合较好,验证了仿真模型的可靠性,此研究对于提升液压支架的焊接质量具有一定的参考价值。
In order to meet the needs of the development of hydraulic support in the direction of large-scale, the related structural parts will inevitably become thicker and thicker, which puts forward higher requirements for welding technology. Q550 high strength structural steel is a common material used to make hydraulic support structure. Taking this material as an example, the temperature field and stress field during multi-pass welding of thick plate and the distribution of residual stress after welding are studied. By comparing the simulation results with the experimental results, it is found that there is a good agreement between the two, and the reliability of the simulation model is verified.
