Establishment of vibration model and experimental analyses of workpiece with variable mass and diameter in turning process
摘要
Abstract
Vibration dynamic model of workpiece subjected to axially moving three-dimension load along its axis is established in turning operation according to actual turning process, in which the effect of time-varying diameter and mass of workpiece is considered. Moreover, the equation of motion of the model is solved and computed with Matlab; dynamic response of workpiece is obtained under different cutting conditions with consideration of the effect of time-varying diameter and mass of workpiece. The computational results show the time-varying diameter and mass of workpiece have an obvious influence on the dynamic response of workpiece, and moving speed of load has a distinctive effect on amplitude of vibration of the shaft. Machining the shaft in turning operation, experimental result is basically in good agreement with the computational one of the model, which accords with the actual turning operation.关键词
