摘　　要：通过分析切削过程中影响柔性轴尺寸误差的因素,采用有限元分析和实验研究相结合的方法,定量研究了切削力作用下柔性轴的变形情况。结果表明:在切削力的作用下柔性轴呈两端变形小、中间变形大的腰鼓形。这一研究结果为正确预测柔性轴尺寸误差提供了理论依据。The flexible shaft bends easily under the external forces because of its large slenderness ratio .This paper analyzes the factors influencing the bending distortion of the flexible shaft ,calcutates the deformation of the shaft under the cutting forces quantitatively through the combination of finite element analysis and experimental study .The results show that the shaft will have a drum shape after cutting ,providing theoretical bases for the prediction of the dimension error of flexible shaft .
