This paper deals with a theoretical stability analysis of flexible bellows subjected to oscillating internal fluid pressure excitation. In the theoretical stability analysis, the bellows are treated as a Timoshenko beam including the effect of the internal fluid pressure and fluid flow. Mathieu's type equation is derived from the basic equation of the bellows. The natural frequencies of the bellows and the parametric instability boundaries are calculated. As a result, it is found that primary and secondary parametric vibrations occur in the bellows due to the oscillating internal fluid pressure and oscillating fluid flow. And the parametric instability regions are examined for various parameters.
