ABSTRACT
This chapter presents a low cost Machinery Fault Simulator (MFS) for teaching and research and validate the proposed MFS through experiments. For exact diagnostic and prognostics, the machineries are tested using a MFS. Since the MFS is a good example for an integrated mechatronics system, it is used to teach theories of vibration, as well as principles of mechatronic systems. However, the commercialized MFS is too expensive to equip several systems for education, and the costs of sensors and data acquisition devices are too high even if the system is built in a laboratory. Machineries consist of many parts, so that a small fault in one part can create a great expense for maintenance due to the failure of the entire system. Correlation analysis was carried out to ascertain the possibility of simultaneous sampling of the proposed system. In particular, the total system, including the test bed, sensor, data acquisition, and analysis program can be fabricated at low expense.
