Dynamic Stability and Natural Frequency of Composite Corrugated Bellows Expansion Joint

Abstract:

The paper deals with dynamic stability and natural frequency of composite corrugated bellows expansion joint. In this simplified formulae are developed by a thin walled pipe model. The dynamic model determined by integration method. According to the EJMA formulae the torsional stability calculation is modified using two different equivalent radii. The torsional natural frequencies are calculated using the formula based on equivalent thin walled pipe model. The modified formulae are verified by those from a finite element model and good agreement is shown between the simplified formulae and the finite element model.
