Chaotic Motion in Nonlinear System with Coulomb Damping
Chaotic motion of a harmonically excited nonlinear system with Coulomb damping is investigated in a range of excitation frequencies.Phase plane diagrams,Poincare’maps, time histories and power spectral densities are obtained and Lyapunov exponents are computed.Period doubling route to chaos is observed in certain frequency ranges which is explained using harmonic balance analysis.The stability of the strange attractors with respect to initial conditions is investigated by interpolated cell mapping technique.
