In this study, a static and dynamic characteristics analysis system for machine tool spindle systems with 3 lobe sliding bearings is developed based on Timoshenko theory, finite element method and windows programming techniques. And the characteristic values of 3 lobe sliding bearings such as eccentricity ratio, attitude angle, friction coefficient, stiffness coefficients, damping coefficients and so on, are determined by using the thermal equilibrium condition of spindle sys-tems. Since the developed system has various analysis modules related to static deformation analysis, modal analysis, fre-quency response analysis and so on, it can be utilized to perform systematically the design and evaluation processes of spindle systems with 3 lobe sliding bearings under windows GUI environment.
