TZ系列子午加速式轴流通风机的噪声控制及气动噪声特性

The Noise Control and the Aerodynamic Noise Performance of the TZ Series Meridionally Accelerated Axial-flow Fans

通过优化的消声降噪结构设计和气动设计，有效地控制TZ系列子午加速轴流通风机的噪声水平；通过风机的气动噪声频谱特性试验和分析，提出进一步改善噪声特性的研究方法。

Optinized ahsorbing structure and aerodynamic design can effectively control thesound level of TZ series meridionally accelerated axial-flow fans. The spectrum test and analysisof aerodynamic noise suggests a stydying procedure for the further improvement of sound performance.
