基于ANSYS的可转位刀片有限元分析

采用有限元软件ANSYS构建出具有复杂截面几何特性、复杂边界条件的硬质合金可转位刀片三维有限元模型。通过切削力试验测得切削力,在ANSYS中加载求解,进行应力场分析,计算出刀具的最大应力等,利用ANSYS的有限元分析和计算机图形学结合功能,显示三维应力等值线(面)、位移等值线(面)。结果表明该有限元模型更接近硬质合金可转位刀片的真实形状,可方便地进行硬质合金可转位刀具的抗弯强度和抗压强度校核,有利于对切削过程中的力学特性进行深入研究,为硬质合金可转位刀片的优化设计提供基础理论。

FEM Analysis and Study of the Turning Carbide Indexable Inserts

In this paper,finite element method is applied,the 3D finite element model of the turning carbide indexable inserts with complex geometry properties and boundary condition is constructed using Finite Element soft ANSYS.Finite Element soft ANSYS can analyze the stress field,caluclate maximum stress,and display stress and displacement isoline.The result shows that the FE model is more approaching to the true cutting tool,and the cutting force is been gotten by the cutting experiment.This is advantage for the investigation on mechanical characteristics of the turning carbide indexable inserts in cutting.
