| Abstract: | Critical speeds and mode shapes of high speed hollow spindle in fancy yarn spinning frame are calculated by using finite element method in this paper. The influences of structural parameters upon critical speeds are also analysed. Modal measurement of the samples of spindle desiged and manufactured by authors are tested in order to verify theoretical calculation. The results of amplitude at top of spindle and niose under various speeds show that the spindle satisfies designing requirements and can be used in spinning. |
