Vibration measurement system for quality control in the company DavMotor Ltda

Abstract

Currently, the proper use of existing technologies applied to quality control adds value to production processes. Dav Motor Cia. Ltda. is an industry dedicated to the design, manufacture and assembly of bus bodies; which has as a fundamental part of its production process the quality control of its units, where vibration measurement is made based on a people’s perception. For this reason, this paper presents the development of an automatic and wireless method of vibration analysis to monitor the adjustment and sealing of windows, lids, warehouses, boards, doors and trunks of the bodies. Measurement dots were selected according to non-conformity found as well as final client complaints, who have requested warranty. This situation generates extra-costs because of coverage of factory failures to the company. The vibration analysis makes use of ZigBee technology, Arduino microcontroller and its compatible components for the reading, processing, display, and analysis of vibration data generating reliable quality control reports and adding value to the production process. Thus, greater synergy has been created between cyber-physical systems and industrial processes, promoting continuous improvement as well as greater client satisfaction.
