Online Forecast of Fatigue Life in Welded Grider of Bridge Crane

摘要：

It is very important to forecast the fatigue crack development upon welded girder of bridgecrane during use.When it happens,it will have a lot of clout with performance of enterprises.Forsecurity purpose in use,ANFIS model is built to predict the length of the fatigue crack extensionabout welded girder of bridge crane.Membership function is adjusted according to inputs and outputsof fuzzy reasoning,and appropriate fuzzy regulation numbers are chosen.The model which is closestto the real development of fatigue crack is built with the help of the If-Then rules.According to theresult from the fatigue experiment of the welded girder of bridge crane,ANFIS model,ANN modeland Three Order Spline Interpolation model are respectively built.After analysis and verification,it isobvious that ANFIS model is more accurate and feasible.
