Finite element analysis of inner hole stress of turbine shrunk - on disc 汽輪機(jī)套裝葉輪內(nèi)孔應(yīng)力有限元分析
This paper discussed the development general situation of the domestic and international super high pressure vessel first , and then the calculative method of stress and the homologous strength theories about the single - layer ordinary round super - high pressure vessel , single - layer autofrettage thick wall round super - high pressure vessel and shrunk - on double - layers round super - high pressure vessels were elaborated systematically 本文在論述了國內(nèi)外超高壓容器的發(fā)展概況的基礎(chǔ)上,較為系統(tǒng)地闡述了單層普通圓筒形超高壓容器、單層自增強(qiáng)厚壁圓筒形超高壓容器、雙層縮套圓筒形超高壓容器的應(yīng)力計(jì)算方法及相應(yīng)的強(qiáng)度理論。
