Abstract
In the present study, we perform the systematic survey for the effect of friction boundary on deformation behavior of coned disc springs subjected to axial load. A simplified method for predicting the load-deflection curves, including hysteresis due to friction at edges, is proposed based on the equivalent of energies and the friction law. The validity of the present method is then verified by the comparison of FEM analysis results obtained under various conditions. Furthermore, the resonance characteristic of coned disc springs subjected to axial forced vibration is examined by using the proposed method. The effect of friction boundary, i.e. frictional damper, is examined for several frictional conditions and forced amplitudes.
