概要:

金沢大学理工研究域機械工学系<br />目的巻糸体を回転させる工程において大気圧が回転動力に及ぼす影響について, 周囲の空気をかく拝する動力と糸を解じょさせるための動力の両面から検討することを目的とした.成果かく絆動力は電動機の反力を, 解じょの動力はラッシングエンド半径を測定する方法によって次の結果を得た.(1) 圧力と空気の密度はほぼ比例しているので, 周囲の空気をかく搾する動力は圧力の減少にともなって0.8乗に比例して小さくなる.(2) 減圧をするとラッシン … グエンド半径は広がり, これを保っための動力は増加する.バルーンの場合も同様である.減圧の小さい場合, 繊度の小さい糸では半径の広がりも小さいが, 繊度の大きい糸は広がりも大きく動力の増加割合も大きい.(3) 上記の結果, 繊度の小さい糸で巻糸体径が大きい場合は圧力を減じるとエネルギー低減効果がみられる. The relationship between the atmospheric pressure and the energy consumption was studied in the process of rotating yarn package. Both powers caused by the force of stirring the air around the yarn package and by the tension of unwinding a yarn were investigated at several kinds of atmospheric pressure. The power in order to stir the air was obtained by means of measuring the power of the motor to rotate the yarn package and the power in order to unwind a yarn was obtained by means of measuring the lashing-end radius. Results obtained are as follows : (1) The. power to stir the air around the yarn package varies proportionally to 0.8 power of the atmospheric pressure around it, because the air density is almost in proportion to the atmospheric pressure.(2) The lashing-end radius increases with reducing atmospheric pressure, so the power to keep the shape of the lashing-end curve increases. The ballooning phenomenon also has the similar tendency. Under small amount of pressure reduction, a fine yarn has a little enlarged lashing-end radius, on the contrary, a thick yarn largely increases its lashing-end radius, the power loss largely increases.(3) For the reason above, reducing atmospheric pressure takes effect for saving energy in the case of a fine yarn and of a large package.<br />出版社照会後に全文公開 続きを見る
