空气锤进排气噪声控制用消声器的试验研究

Experimental study of mufflers for controlling air-entrance exhaust noise of an air forging hammer

分析了空气锤进排气噪声的特性．全面深入地试验和分析了，不同基本滤波单元及其组合的 消声器实际应用在Ｃ４１－１５０型空气锤时对进排气噪声的降低性能，并取得了显著的降噪效果。

Characteristics of air-entering and air-exhaust noise generated by an air forging hammer are analyzed. Properties for reducing the noise are tested and ananlyzed when various basic wave filtering units and their combination are used for controlling the noise generated by C41-150 air forging hammer. Noticeable noise reduction is achieved.
