Three dimensional finite element analysis and optimal design of cast-iron bronze-inlaid gate

摘要

The three-dimensional finite element model of the body of cast-iron bronze-inlaid gate is established to calculate its deformation and stress. By calculation, we obtain the law of deformation and stress under static water pressure. Then we optimize the structure of the body of cast-iron bronze-inlaid gate vie above calculation results. To validate the effect of proposed method, an engineering example of 100mm x 1500mm gate in a certain sewage process plant is introduced. The comparisons are made between the calculation results of the proposed method and those obtained by conventional design. The comparison results show that three dimensional finite element methods can obtain the actual stress and deformation of the gate body under static water pressure. In addition, we further optimize the structure and dimension of the cast-iron bronze-inlaid gate. The final optimization results show that the proposed method can reduce the weight of the gate by 20% compared those results by conventional design.
