Thaum rotating slender ncej, qhov ua rau deformation thiab vibration yog raws li nram no:
(1) Lub workpiece yog khoov thiab deformed los ntawm kev txiav thermal elongation.
(2) Lub workpiece khoov thiab vibrates nyob rau hauv qhov kev txiav txim ntawm txiav quab yuam.
(3) Kev vibration los ntawm qhov hnyav tuag thiab deformation ntawm workpiece.
(4) Nyob rau hauv qhov kev txiav txim ntawm centrifugal quab yuam, khoov thiab vibration ntawm lub workpiece yog aggravated.
Cov kev daws teeb meem tau txais suav nrog:
(1) Siv lub hauv paus ncej;
(2) Siv cov cuab yeej pob taws;
(3) Txo thermal deformation;
(4) Tsim nyog xaiv cov geometry thiab txiav cov khoom ntawm cov cuab yeej tig.
