Vibration isolation pad for medical purposes: modeling and simulation

Abstract

This project aims at establishing new research about protecting sensitive human beings from vibration syndrome. The main application targeted here is the protection of patients undergoing the Magnetic Resonance Imaging test where noise and vibration can cause severe damage to the test results. Stability and accuracy are very important issues in this medical test. An active vibration isolation pad will be designed and manufactured in this research where the force of the vibrating human body is measured and compensated to be fed back to a linear piezoelectric actuator to isolate the disturbing source of vibrations from propagating into the patient’s body. This paper presents analytical and numerical models for the vibration isolation system where the Integral Force Feedback control technique is applied. The results prove high authority and robustness for this control technique especially on the first vibration mode.
