TÓM TẮT
Mechanical vibrations occur mostly in production systems, and it also causes some damage. To detect the cause of this situation, the collection of parameters during operation is essential. This article uses an intermediate control circuit to convert the energy generated by mechanical vibration into electrical energy (current and voltage), in which the piezoelectric sensors or piezoelectric beam are placed on the structures to be measured, we will receive oscillations at different frequencies, so that we can analyze the damage caused by vibration and evaluate the application range of piezoelectric sensors and piezoelectric beam on a case-by-case basis. The purpose of this paper is to use Bond-Graph to optimally simulate this energy recovery process. This is also a very good solution for generating energy for the SHM system from other mechanical energy sources.
