3D Finite Element Calculation and Analysis of Two2way Water Sealing Cast Iron Gates
摘要
Abstract
Athree2dimensionalfiniteelementmodelofcastirongateinahydraulicprojectwasdevelopedusingANSYSsoftware.Under the working conditions that the forward and reverse head difference was 10 m, the maximum stress and deformation were calculated and analyzedusing thethinplatetheoryandthree2dimensionalfiniteelementmethod.Theresultsshowedthattheerrorsofmaximumstress and deformation are as high as 30%~ 50% for the tw o methods. The calculation results obtained from the traditional empirical formula were more conservative, which can cause the increasing of manufacturing cost of cast iron gate, especially when the maximum stress and deformation w ere not at the same place under reverse head. There were deficiencies in analyzing the allowable stress intensity and stiff2 ness required by relative standards according to the compression/tensile strength of the cast iron gate material and the stress and de2 formation variations of gate under inverse/reverse force. In this paper, the optimization scheme of arrangement type and section size of the gate was proposed in order to reduce the manufacturing cost.关键词
