摘　　要：摩擦摆系统（ＦＰＳ）的微幅振动方程，运用等效非线性系统法预测了ＦＰＳ系统对高斯白噪声激励的稳态随机响应。所得解析结果表明，体系滑动转角和速度响应具有复杂的非高斯分布特征。Based on the micro-amplitude vibration equation of friction pendulum systems FPS, the steady-state random responses of FPS to Gaussian white noise actions are forecasted by means of the equivalent nonlinear system method. The obtained analytical solution indicates complex non-Gaussian distribution characteristics of the angle of rotation and its velocity of FPS.
