A Review on Stiffness Calculation of Machine Tools
摘要
The stiffness of a machine tool directly affects the accuracy of the processed parts. The stiffness analysis of a machine tool is an essential task in the design and manufacturing process of a machine tool. The calculation methods for machine tool stiffness are constantly updated. Initially, static analysis was conducted on machine tool modeling based on traditional formulas of theoretical mechanics and the geometric structure of the machine tool. In recent years, finite element methods were used to calculate the static stiffness of the machine tool. A lot of research has found that there is a significant difference between the dynamic and static stiffness of machine tools during operation, calculation and analysis of the dynamic stiffness of machine tools have been carried out by finite element analysis software. This article provides a brief introduction to the stiffness calculation methods of the machine tools.
