摘　　要：根据LES和FW-H声学比拟理论,采用计算流体力学数值模拟软件,研究调节阀在相同流量,30%、60%、100%开度和不同流量,在1 kg/s、2 kg/s和3 kg/s质量流率下的阀门内部噪声特性和声振耦合情况下的结构强度分析。结果表明:阀门开度越小,速度越大阀门内部流场波动越大,声压分贝越高,结构强度越低;阀门开度越大,质量流率越小,噪声分贝越低,结构强度越高。According to the acoustic comparison theory of LES and FW-H,the numerical simulation software of computational fluid dynamics is used to study the regulating valve at the same flow rate,30%,60%,100%opening and different flow rates,at 1 kg/s,2 kg/s and 3 kg/s Internal noise characteristics of the valve at s mass flow rate and structural strength analysis in the case of acoustic-vibration coupling.The results show that:the smaller the valve opening,the greater the velocity,the greater the fluctuation of the internal flow field of the valve,the higher the sound pressure decibel,and the lower the structural strength;the larger the valve opening,the smaller the mass flow rate,the lower the noise decibel,and the lower the structural strength is higher.
