The existence of grazing bifurcation involved in the period-doubling bifurcation is shown clearly. The effects of the random excitation are studied by defining a measure of the stochastic response. The idea that the random factor can change the property of the system in some conditions is proposed. Numerical simulations show that the method is effective. %K non-smooth system %K two-degree-of-freedom impact oscillator %K grazing bifurcation %K period-doubling bifurcation
