Abstract
Predictive maintenance is generally recognized as the best maintenance strategy for most industries. Among the possibilities, vibration-based condition monitoring is considered the most cost-effective, due to its fast response to changes in the system. In order to study machinery fault vibration signals, several studies in the literature utilize SpectraQuest’s “Machinery Fault Simulator” (MFS) -- a test bench that emulates a machine. The measured vibration response of a machine or equipment is a combination of the applied excitation and the dynamic response of a system. Modal analysis is a tool that obtains the dynamic response of a system. Therefore, the modal analysis of the MFS is a topic of interest. This article presents the Finite Element Method (FEM) and experimental modal analysis of SpectraQuest’s ``Machinery Fault Simulator''. It focuses on the bearing base, bearing support, C-shaped beam and the assembly of these components. With the assistance of BK Connect software, experimental tests were made. The individual components were excited with an impact hammer and the assembly with a shaker. The experimental results were used in order to adjust the FEM simulation, made with the COMSOL Multiphysics software, with parameters such as the material elasticity, density and damping. The numerical model is able to represent the analysed components of MFS's test bench
