基于ANSYS的平面端铣模态及切削响应分析

以某大刀盘端铣切削系统为研究对象,使用ANSYS软件对其进行模态分析,结果表明,结构前六阶固有频率相对较高,远离切削系统的工作频率,不会引起共振。另外,在模态分析基础上,基于切削力对切削系统进行了动态响应分析,分析了刀片的加速度响应。该研究为平面端铣提供了振动分析基础,同时对于提高切削系统的结构性能具有重要意义。

In this paper,a large cutter head end milling system is studied by ANSYS software.The model results show that the first six natural frequencies of the structure are relatively high and far away from the working frequency of the cutting system.In addition,the dynamic response of the cutting system is analyzed based on the cutting force.The analysis results include deformation and acceleration response of the system.This study provides a basis for vibration analysis of plane end milling and is of great significance for improving the structural performance of the cutting system.
