Mechatronic Concept for Airflow Tests Laboratory Equipment

摘要

The paper presents application of the mechatronic concept for laboratory test to support a research activity. Laboratory test is taken into account as set of processes for which some number of environmental parameters must be controlled. This paper describes the laboratory stand for investigations of airflow phenomena, where modern data acquisition system is applied to control pressure, temperature and velocity of the air stream. To acquire and process a large number of data, the idea of virtual instruments is introduced to control system. Modern, high-level graphical language was used and the author's program was developed. The presented solution of the laboratory stand allows increasing the accuracy of measurement, it is possible to observe all necessary parameters as rescaled to standard units and use this information in process steering. All technical solutions applied in the system assume flexibility for changes because of additional sensors, actuators and new signal processing and steering procedures.
