| Summary: | With consideration of damping,bearing clearance and gear backlash nonlinearity,a translational-rotational dynamics model of gear-rotor-bearing is built based on the Lagrange equation.The dynamics equation can be non-dimensionalized and simplified to an unified matrix form.By using MATLAB/SIMULINK,the numerical simulation of gear clearance nonlinearity dynamics model is carried out.Through building the simulation model,the nonlinearity vibration research in some parameter fields is carried out,the influence of parametric variation on system steady state response is analyzed.The results indicate that when the excitation frequency is smaller,the system has a period-1,non-harmonic steady state response.As the frequency increasing,the solution bifurcates into the period-2,sub-harmonic vibration response,and then into the period-4,sub-harmonic response.Finally,the steady state response becomes chaotic.The numerical simulation result also illustrates that the bearing clearance enhances the system nonlinearity.The SIMULINK can be used for more complicated model to obtain the dynamic response,which provides a method for deeply researching on the dynamic behavior of gear nonlinear system. |
