Analysis of Pneumatic Vibration Isolator Considering Diaphragm Stiffness

Abstract:

Article Preview

An accurate model of pneumatic isolators is important for its structure optimization and controller design. Previous researches show that an isolator model including the diaphragm effect which is neglected before can predict the isolator response more accurately. Since the diaphragm is often made of reinforced rubber material and has an irregular shape, it is not easy to obtain its parameters with experimental or computing method. A finite element analysis method for estimating the diaphragm stiffness is proposed in this paper, and experimental results suggest that a new model including the diaphragm stiffness correspond to the isolator behaviors more accurately.
