half-amplitude point 中文意思是什麼
half-amplitude point
解釋
半幅度點-
Contrastive tests of damping aluminum - alloys, zinc - alloys and 45 # steel are carried out at the case of equal stiffness. the test results show that when the rocker bar is made of damping aluminum - alloys or damping zinc - alloys, the strain amplitude at the middle point of connecting bar is half of the one when the rocker bar is made of 45 # steel
在等剛度條件下對鋁基、鋅基阻尼合金和45鋼阻尼減振作川進行了對比實驗,實驗結果表明搖桿為鋁基和鋅基阻尼合金材料時,連桿中點動態應變曲線幅值只有45鋼時的一半左右,而且隨著曲柄轉速的提高,阻尼合金的減振效果更加明顯。
