| Abstract: | Using piecewise linearity system theory, the nonlinear response of a clearance-restriction cantilever beam
system to a harmonic
excitation is researched. Firstly, the dynamic model of this system is built.
Based on the transmission function, the dynamical equation and its
solution are derived. The obtained numerical solution show the change
feature of the dynamic response character with the excitation frequency,
excitation amplitude, contact rigidity and contact dumper. |
