1、首先在Workbench中選擇Bladegen模塊勾選創(chuàng)建輪轂和創(chuàng)建所有葉片選項(xiàng)選擇徑向葉輪標(biāo)簽,并輸入Z值和R值(橫軸為Z向,縱向?yàn)镽)。選擇厚度/角度模式輸入葉片包角140度,厚度值及葉片個(gè)數(shù)為7進(jìn)入設(shè)計(jì)總窗口Themostcriticaloperationinthemeridionalviewistodefinetheshapeofthehubandshroudcurve.TheendpointsforthesecurveswerespecifiedwhenInitialDesignParameter

3、特性進(jìn)行修改。雙擊各點(diǎn)修改坐標(biāo)值來定義進(jìn)口和出口截面1.Doubleclicktheshroudinletpointatthetopleftofthemeridionalview.2.ThePointLocationDialogwillopen.TheHorizontalvalueistheAxiallocation(Zco-ordinate)andtheVerticalvaluerepresentstheRadius.3.Enter-10and110forthehorizontalandverticalv
