ABSTRACT
From an experimental perspective, this paper investigates the transverse vibration present in an axially travelling belt undergoing uniform motion with constant travelling speed. Application of a control of the belt speed, using Matlab, a Code Composer Studio (CCS) and the available complementary embedded tools, a stepper motor DSP control was obtained automatically by using a graphical method to establish the stepper motor movement models within a Simulink environment. By changing the tension of the belt and the rotational speed of the stepper motor, the natural frequency of the travelling belt was studied. The response waveforms, spectral content and phase diagrams were obtained by measuring the transverse vibration displacement under different conditions. A nonlinear model for the experimental moving belt system was developed and numerical solutions calculated. Subsequently, the nonlinear response behavior of this model were validated by the results of the experiment. It was shown that there were many scenarios for which the system can exhibit periodic motion, chaotic motion and beat frequency phenomena to be present and measured in the vibration of the axially travelling belt.
