Numerical Simulation Study of the Influence of Turning Depth on the Bending Vibration Mode of Work-Piece

Abstract

The mechanical models with and without thimble constraints for the turning work-piece are built respectively, applying ABAQUS software to analyze the modes of work-piece, then the law of the influence that different turning depth on the bending modes of work-piece is obtained. The study indicates that each-order natural frequency increase gradually in linear form for the work-piece without thimble constraint, while for the work-piece with thimble constraint, the natural frequency of the first four orders decrease linearly with the increase in the turning depth, but the change of high order frequency is relatively complicated.
