Research the Influence of Curved Shape on the Multilayer Bellows

Abstract

As a cylindrical thin-walled container, multilayer bellows has greater bit shift compensation, vibration and noise reduction capabilities while the appropriate metal and viscoelastic damping materials are adopted. Finite element models are adopted to analyze the loss factor of multilayer bellows in ANSYS. The strain energy distribution of Multilayer bellows and viscoelsticity layer are given. According to the strain energy, the influence of structural parameters on the loss factor is studied. The results show that the loss factor can be improved by employing the curved shape with big wave height, small wall thickness, small wave pitch and diameter of bellows.
