Analysis on Effect of Excitation Frequency on Nonlinear Characteristics of a Gear Pair System Based on Numerical Simulation
نویسندگان
چکیده
A nonlinear dynamic model of the geared rotor system, with consideration of the bearing clearances and gear backlashes, is established. A numerical algorithm based on Runge–Kutta-Butcher method is used to study the nonlinear behaviors of the system accounting for the effects of different excitation frequency. A detailed parametric research is conducted to analyze the influences of the excitation frequency on the nonlinear characteristics of the system. The final goal of the work is to study bifurcation and chaotic behavior of a gear pair model that includes nonlinearities due to bearing and teeth backlash. The analyses are performed in a parametric manner using non-dimensional excitation as bifurcation parameters. The results show that the different excitation frequency can significantly influence the nonlinear dynamic responses.
