Research on Dynamic Balance Control of CT Gantry Based on Multi-Body Dynamics Algorithm

In order to improve the stability and image accuracy of the CT scanner frame during high-speed operation, the dynamic characteristics of the rotating system and the unbalanced excitation mechanism are investigated on the basis of multi-body dynamics algorithms, and a dynamic balance control system including adaptive PID and real-time compensation strategies is constructed. The control strategy is verified by ADAMSMATLAB joint simulation and experimental platform, and it is analyzed that the method can effectively inhibit the vibration perturbation caused by the coupling of eccentric mass and structure, significantly shorten the response time and reduce the amplitude of steady-state vibration, which has high engineering adaptability and popularization value.
