بررسی عددی و شبیه سازی رایانه ای مدل فنر- قطعه

  We present numerical solutions of the equations of motion of the driven spring-block model with stick-slip dynamics. The system consists of an array of N masses which describes the statistical and dynamic properties of dissipative systems. In this study, we are interested in very low and very high velocity regimes. We show that there is a clear shift in the distribution of slip-force when we move from a low velocity regime to an intermediate one and then to high velocity regime. The observed transitional behaviour corresponds to the Gaussian distribution in low velocity, to -shape behaviour in the intermediate velocity and to an inverse-Gaussian distribution for the high values of velocity.
