Applying Wireless Transmission for Aluminum Alloy Wheel Cornering Simulation and Testing

Abstract

This study adopted finite element analysis (FEA) to conduct tests and simulations on the bending moment of truck wheels. Based on the simulated analysis using ANSYS Workbench software, a three-axis strain gauge was attached to locations with substantial stress variations. The strain gauge was converted into voltage. Amplification and filtering circuits were adopted for signal processing, and the processed signals were subsequently entered into the microcontroller unit. Simultaneously, a universal asynchronous receiver/transmitter (UART) communications protocol was applied for communication with the Bluetooth wireless module. The accessed signal was then transmitted to the receiver end through wireless emission. The detection interface at the monitoring end was designed using LabVIEW software, enabling operators to observe the stress and strain for wheels under various test conditions. The acquired data were stored in a computer for future reviews and analysis.
