摘要
A number of strategies for optimal design of the gas turbine disks are proposed,which include separation of tenons design from disk design,rational simplification of structural model,check on local constraints,optimal design based on elastic analysis and further check based on elastoplastic analysis,multi level optimization by grouping design variables.According to the strategies a computer program TDSOS is developed for practical use.By applying the strategies and the program TDSOS,shape optimization of gas turbine disk with light mass and low stress level can be obtained and the contradiction among high performance index,reliability and long life expectation is better solved.
