Dynamic behavior of rock anises based on transfer function
【摘要】 根据外力下岩体的破坏特点,分析了其主要影响因素,根据平面摩擦行为,建立了岩体动态稳定性分析模型,并从模型的动力学特点出发,建立了运动学微分方程,引入传递函数法求解的概念,通过对微分方程进行系统的非线性动力学分析研究,研究了系统的运动稳定性。
【Abstract】 The main factors influencing the rock system are analyzed in terms of the characteristics of rock fracture under the driving.An analyzing mode of rock dynamic stability is established in consideration of the plane friction behavior,and based on the kinetic characteristics of this model,a kinematical differential equation is established.The concept of transfer function solution,the motion stability of the rock system is also analyzed through a non-linear kinetic study of the differential equation.
