Purpose: to study the transients in the vibrating machine that accompany the start from rest and run out.
The studies were performed on a laboratory vibrating screen. The screen is driven by an adjustable drive - a single-shaft inertial vibrator, which has imbalances with variable mass. The screen has a resonant setting, ie h natural oscillation frequency is less than the frequency of the forcing force of the drive.
The GY-521 module with the MPU6050 chip is used to measure the kinematic characteristics. This module allows you to measure linear acceleration and angular velocity.
The graphs show typical graphs of changes in the acceleration points of the vibrating screen box at full cycle: from start to complete stop.
The graphs show the run-out (stop) areas of the screen. There is an increase in the amplitude of the oscillation of the acceleration of the screen box during the passage of the resonant frequency. This phenomenon is characteristic of the vibrating machine with a resonant setting.
