| Abstract: | The dynamic characteristics of disk spring taking account of effect of static load,nonlinear restoring force and combined Coulomb and viscous damping are presented.Natural vibration of the nonlinear disk spring system is investigated by using the Fourier series analysis and average method.Various factors that effect the amplitude and frequency of the natural vibration are discussed.The steady forced vibration of the nonlinear disk spring system under base excitation is obtained by using the Fourier series analysis and harmonic balance method.The vibration reduction performance of disk spring is analyzed through detailed parametric investigation.The stability of the steady solution is investigated by using a modified stability procedure. |
