摘要: The method of averaging is applied in this paper to deal with a primary resonanceof a three circular plates torsion vibration system having cubic. nonlinearities whieh isexcited by a simple-harmonic excitation. Bifureation equation of the steady stateresponse is obtained and its singularity, analysis is given. The results of theoreticalanalysis are shown to be in good agreement with experimental ones.
