Based on ANSYS Workbench High Speed Electricity Spindle Dynamics Characteristic Analysis

摘要

This paper describes the inherent characteristics, dynamic response and dynamic stability dynamics of vibration capability that impacts of high-speed electric spindle. Taking the high-speed, high-power electric spindle milling center on as the object of the research, modal analyzing of electric spindle with the finite element software ANSYS Workbench, researching the spindle modes, natural frequencies and critical speed of electric spindle, to get each frequency and vibration type, pointed the affection of what spindle away from the anti-vibration frequency requirements, well before bearing stiffness and damping of the vibration to the spindle system. It provides the necessary basis for further dynamic analysis by modal analysis.
