Measurement, Control and Automation Applied to Structural Durability Testing for Vehicles

This material presents a project for data acquisition applied to monitoring climatic road simulators. The developed system acquires accelerometers and thermocouple signals from the vehicle suspension and body, point-by-point. This implementation allows real-time monitoring during tests, with the objective of making is autonomous. The platform used for the data-logger and automation system is composed by analog and digital input/output, TCP/IP and OPC protocols. The result obtained by this approach consisted mainly on the possibility of mapping the vehicle response throughout the tests, the integration of climatic and vibration control and overall contribution to a higher use of road simulators.
