Optimizing the braking system for handling equipment

Abstract

The article is focused on optimizing the friction disc plates of the braking system integrated into the drive wheel of an automated guided vehicle. The introduction is focused on the application of these types of braking systems. In the next step, the individual mathematical parameters and the acting forces in the braking system are expressed. Using the equation of motion that is written in Matlab, the braking distance and the stop time are graphically expressed. During the Matlab simulation, different diameters of the braking plates are monitored to determine the braking distance. The permitted pressure in the braking plates during the test must not exceed the specified pressure of 2 MPa. The functionality of the braking plates is ensured by hydraulic power. Part of the wheel is a sensor that monitors the speed during braking. Ultimately, a continuous reduction in kinetic energy is achieved without vigorous blocking of the slats during braking. The acquisition of the paper is the output of numerical calculations, which are necessary for the correct design of the wheel with the integrated braking system.

“…1. Concept of drive wheel with integrated multi-disc brake [4,6] The brake system is integrated into the free space drive wheel of the automated guided vehicle (AGV). This type of multi-disc brake is currently the subject of research at the Department of Design and Mechanical Elements of the University of Zilina in Zilina.…”

“…However, as the speed increases, so does the amount of force of inertia applied to the AGV during braking [4,5]. The current electric engine brake is not designed for braking at high speeds, and the vehicle is not able to stop at a safe distance in crises (sudden braking) [6]. During braking, the drive wheels are locked, and the vehicle tends to slide a few tens of centimetres forward.…”
