blade frequency force
常见例句
- The cutting noise mainly root in high-frequency vibration of the circular saw blade induced by the cutting force.
锯切噪声的主要来源是圆盘锯在锯切力作用下的高频振动发声。 - Though asymmetry stator mistuned may result in bigger amplitude aerodynamic force with the same frequency as rotational speed, it could reduce effectively the aerodynamic force of blade as a whole.
不对称叶栅非谐设计虽然会引起与转速同频的较大幅值激振力成分， 但从整体考虑可有效降低叶片振动应力。
