Calculation and Study on Torsional Stiffness of Big Power Laminated Membrane Coupling

As one of the most important parameter in the analysis of shafting torsional vibration, the torsional stiffness of laminated membrane coupling is a basic index of coupling's excellent characteristic which must be considered. It is made detailed analysis to membrane stress of laminated membrane coupling which transfer bigger torque with finite element method, the distribution of membrane stress is pointed out. and calculation and analysis of its torsional stiffness is made. The results of torsional stiffness are comfortable compared with the same type overseas product. At the same time, It is pointed out steel-frame structure model is not suitable for calculating laminated membrane coupling of big power. The results of this paper provide important referrence for us to research and develop laminated membrane coupling of bigger power.
