Self-excited two-mass system with soft impacts

Abstract eng:
To a basic one-mass self-excited system a tuned absorber is attached the motion of which is influenced by soft impacts. The self-excitation is considered as of van der Pol type one. The stops are symmetrically situated to the absorber mass equilibrium position. The results of numerical simulation are presented in diagrams showing the measure of extreme deflection of the basic system mass to the amplitude of the basic system vibration without absorber in dependence on the tuning coefficient of the absorber. The following effects are investigated: the ratio of the absorber mass to the basic system mass, the distance of the stops, absorber motion damping, and damping in the stops. Generally the stops do not represent a favourable effect.
