摘要(Abstract):
用非线性动力学的理论研究了通风机噪声问题,从全新的角度分析了气动噪声产生的机理、通风机内气体流动非线性特征及其对气动噪声的影响;同时还讨论了气固耦合噪声的作用机制
The problem of noise of the fan is studied with the non linear theory,from new angle,the producing mechanism of aerodynamic noise,the nonlinear feature of gas fluid in the fall and the influence on the aerodynamic noise is analyzed,furthermore,the mechanism of gas solid coupling is discussed.
