讨论了具有间隙、时变参数和外部激励联合作用的非线性振动问题。提出了用打靶法和连续法求解这一问题周期解的数值方法，并使用一种参数连续法，使奇点处理非常简单。最后给出了一个计算示例，得到了稳定和非稳定的频响曲线。
The nonlinear vibration problem with joint action of gap, time-varying parameter and external excitation is discussed. A numerical method to solve the periodic solution of this problem by shooting method and continuous method is proposed. Using a continuous parameter method, singular point processing is very simple. Finally, a calculation example is given, and a stable and unstable frequency response curve is obtained.
