Analysis of Influence of Bellows Waveform Parameters on Column Instability Based on ANSYS
In order to study the effect of bellows waveform parameters on the instability of bellows column,modal analysis and eigenvalue buckling analysis of bellows were carried out using ANSYS Workbench.Using the method of control variables,the bellows waveform parameters were changed and finite element analysis was performed separately,and finite element analysis was performed for a compound bellows with the same wave number,and the analysis was compared with the stability of a single bellows.The finite element results show that in practice,the occurrence of bellows column instability can be reduced by increasing the bellows wall thickness and wave distance,or reducing the wave height and wave number.When the length of the bellows is long and the wave number is large,the use of multiple bellows is a better choice.
