It is important that constant velocity of gantry of 3D fluoroscopy for correct digital image processing. But constant velocity driving is difficult because gantry has heavy mass and eccentric loads. So a design of control algorithm and performance evaluation are needed for constant velocity of gantry of 3D fluoroscopy. But it is difficult that performance evaluation of control algorithm because of a special quality of 3D fluoroscopy. And flexible model analysis is necessary for resonance and displacement. So motor, reductor and unbalanced gantry of 3D fluoroscopy are designed with multibody dynamic analysis program, and simulation platform is designed for performance evaluation of robust control algorithm against disturbance. Dive performance such as velocity ripple in various condition was observed. So this paper proposes a design of flexible model simulation platform of imbalanced rotor with heavy mass for evaluation of control algorithm for constant velocity.
