Numerical and Experimental Research on Dynamics of Two DOF Vibration System with Piecewise Stiffness
In this paper, the two dof vibration isolation system with piecewise linear vibration isolators under force excitation is analyzed. Isolators with asymmetric restoring forces are considered, and the results of periodic-n and chaotic motions are calculated by numerical simulation. These motions are described by phase plane diagram, spectrogram and Poincaré mapping. The simulation results are experimentally verified. The results that are obtained in this paper would be significant for chaos method to line spectra reduction.
