Study on the Damping of Multi-layer U Bellows Based on ANSYS

摘要

The relationship between wave length, diameter and number of layers and the loss factor of multi-layer bellows was analyzed by using the iterative method of modal strain energy, according to the numerical analysis results of the finite element ANSYS software, the influence curves of different parameters on the loss factor were obtained. The results show that: with bellows wave length and diameter increased, the loss factor are decreased; the loss factor increases with the increase of the number of layers. Finally, the correctness and validity of the finite element model and ANSYS numerical analysis were verified by the experimental method.
