Abstract

Abstract

The exact transfer matrix method was used to analyze the dynamic characteristics of the high-speed spindle system of a precision NC lathe. The method has the advantages of calculation simplicity, high accuracy and easy programming. The coupling stiffness of the double rotors was calculated effectively with FEM.
