Abstract: The nature of the critical damping of a nonlinear vibration system is studied by using MATLAB.The formula for calculating the critical damping and the equation of motion in the critical damping state of the nonlinear vibration system are proposed.The results calculated by the formula and the numerical solution are also compared.

Key words: critical damping, nonlinear vibration system, MATLAB
