Abstract:
A four-degree-of-freedom mechanical system composed of two weakly coupled modules with external forcing is modelled and numerically investigated. Each module contains internal vibro-impact oscillator. The mathematical model is built based on the compliant impacts with realistic nonlinear stiffness and damping characteristics. The model of resistance of motion of the modules assumes conditions possible in real linear rolling bearings. There are presented exemplary bifurcation properties of the system including periodic and chaotic dynamics of the system.
