摘要
Abstract
To enhance the operational efficiency and stability of gas turbines,the modal characteristics of a heavy-duty gas turbine combustion chamber were analyzed using finite element simulation method.The analysis encompassed the combustion chamber with and without reinforcing ribs,involving natural frequency and harmonic response analysis.The results indicated that the addition of reinforcing ribs could reduce the acceleration response peak of the combustion chamber and lower the frequency corresponding to the response peak,thereby facilitating the operation safety of gas turbine.Furthermore,by comparing actual operational data with the results of the finite element analysis,the rationality of the finite element computational method was verified.The research findings can provide technical support for the design optimization of gas turbine combustion chamber.关键词
