-
摘要: 对3种轴流式轮盘在常温和高温下进行了非线性有限元计算,提出了一种应用有限元法计算轮盘破裂转速的破裂准则,得出了3种轮盘的破裂转速;并将计算结果与大变形解析法及试验值作了对比分析。Abstract: 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.
