강력선반용 고 토크 주축계의 동특성 해석

This paper describes the dynamic characteristic analysis of a high-torque spindle system for a heavy duty lathe. In the study, we performanced the analysis of a high-torque spindle system for our heavy duty lathe by using ADROS, which is our own developed S/W for dynamic analysis of spindle system. We get a results some analysis dynamic characteristics of a spindle, such as natural frequency, whirl frequency and critical speed.
