Abstract: The superharmonic resonances
of elastic linkages are studied by using the method of multiple
scales under the excitation of its inertial force. The analyses
demonstrate that the superharmonic resonances caused by the
quadratic and cubic nonlinearities due to large elastic
deformations of the flexible links and multi-frequencies of the
inertial force of linkages are the reason to produce the
critical speeds. The results of explaining of the lower order
harmonic resonances by "1/n" method are verified theoretically.
