 abstract = {Vibrating screens are critical machines in the mining industry. The screen movement is mainly defined by its inclination and vibration amplitude. A proper movement allows correct operation of the screen. Available models cannot simulate motion with high angular displacement, as a startup, shutdown and under loss of stiffness in supporting positions, because these models linearize angular displacement. In this article a 2D 3DOF nonlinear model is proposed, presenting its development, solution and numerical simulations. Simulations deliver how much the direction of each orbit and magnitude of the natural frequency change, with respect to the supports's stiffness. This makes it possible to evaluate the state of the springs to keep the design conditions to ensure high efficiency and detect changes required of them to increase the mean operation time for replacement of the springs.},
