| Abstract: | Taking turbine discs as analyses model,the stresses of which made by several high-temperature alloy are calculated making use of the finite element method.The APDL language is used to design a program for the parametric shaping of the turbine discs,analyze of the stress and the optimizing of the turbine discs.The turbine disc structure is optimized by means of first-order method,and the integration of the parametric modeling and the optimization design is accomplished.The structure of the optimized turbine disc was applied,and the result of the experimentation indicated that the structure is reasonable and dependable. |
