Abstract


A model of mechatronic system with two degrees of freedom containing hardening spring nonlinearity in the mechanical part and softening nonlinearity in electrical feedback loop is presented. The hardening spring nonlinearity is caused by the impacts on the stops with finite stiffness, the softening nonlinearity describes the dependence of output current on voltage input of the power amplifier, in which the limitation of output current occur. The response of the system, the mathematical model of which is transformed into the dimensionless form, is studied for different parameters of nonlinear characteristics.
