Design and improvement of steel liner of Wudongde hydropower station based on ANSYS

According to the structural fo rm of the tr ansit ion o f t he water int ake area in the left diversion tunnel o f Wudong de hy2 dro power stat ion, a larg e hyperbolic steel liner was designed. The static analy sis of the design scheme w as conducted using the finite element softw are ANSYS. T he r esults show ed that the structural stress of the initial design scheme of mo ld is high and the w eig ht is larg e, so the design scheme needs to be impr oved. According to the to po lo gical optim izat ion results based o n WORKBENCH , an impro ved desig n scheme w as pr oposed and verified, which can decrease t he w eight o f mold by 471 0% com2 pared w ith the o riginal scheme. Meanw hile the cost was saved and the stiffness and strengt h of the mold satisfied the construc2 tion requirement. The research results can pr ov ide r eference fo r the similar engineer ing pro jects.
