Determining Structural Resonance Frequency via Low-Cost Micro-Electromechanical Systems

One of the most important tasks in dynamic experimentation and empirical modal analysis is the study of structural responses to a variety of excitations. Generally, such responses can be received from different point parts of a structure. Frequency and time domain analyses utilize these responses to provide information on dynamic features of a structure such as resonance frequency, modal shape, and modal damping. In recent years, there has been widespread progress in the production of micro-electromechanical sensors, and cell phones and other gadgets have utilized this technology. In the following paper, the MPU 6050 module is introduced. Then, the process of implementation and coding of this module is described. Finally, to evaluate the data collecting quality of this module, the results of the experimental models are compared with the finite element results, and the conclusion is made.
