Study for the random responses of sliding systems with hard springs
【摘要】 利用等效线性化方法推导了具有渐硬非线性复位弹簧的滑动系统的高斯白噪声激励稳态随机响应概率分布的解析解。与蒙特卡洛模拟解对比结果表明 ,该解析解能够较好地预测滑移系统的稳态高斯随机响应。
【Abstract】 The analytic solutions of the probability density of the steady state responses of Coulomb sliding systems with gradually strong springs to Gaussian white noise are derived. The results compared with Monte Carlo simulation show that the analytical solutions can well forecast the probability distribution of the steady state Gaussian responses of the systems.
