摘要
论述了焊接残余应力对臂架结构的影响，深入探讨了臂架失稳折臂的机理，并以１６ｔ－３０ｍ门机臂架为例。
This paper explains the effect of welding residual stress on jib structure,It mainly discusses the principle of instability of crane jib,And,taking as an example THE 16t-30m CRANE JIB,the paper expounds the application of welding residual stress calculation to crane jib analysis.
