本文利用航空发动机环行燃烧室测试数据 ,采用线性回归和非线性回归两种方法分别得到了燃烧室噪声总声级和燃烧噪声峰值及峰值频率的拟合模型 ,并利用线性回归模型由燃烧室外部测量结果估算燃烧室内部总声级 ,所提供的噪声数据可供研究发动机燃烧室结构完整性和可靠性时参考 . In this paper, the test data of the aero-engine combustion chamber are used to obtain the fitting models of the total noise level of the combustion chamber and the peak and peak frequencies of the combustion noise by linear regression and non-linear regression respectively. The linear regression model is obtained from the outside of the combustion chamber The measurement estimates the total internal sound level of the combustion chamber and the noise data provided is available as a reference when studying the structural integrity and reliability of the combustion chamber of an engine.
