【Abstract】 WT5BZ]Two dimension non linear finite element calculation has been done for three kinds of axial flow type discs at normal and high temperatures.A burst criterion is presented for calculating the burst speed of rotating disc using finite element method,and the burst speed of the rotating discs is obtained. The results are compared with experimental data and analytic results according to large deformation theory.更多还原
