Résumé fourni par la source

This research is devoted to the electromechanical properties of axle mount devices with piezoelectric elements and their performance under various loading conditions.It performs a complex computational simulation of the interaction between mechanical energy and electrical generation.In the study, the research team examined the technical aspects and scale-up issues of integrating piezoelectric energy harvesting networks into conventional roads.The function of piezoelectric material in car wheels, which senses patient head movement and stability via pressure, is covered in the study.Important considerations include the material's size, voltage, and Deformation.The extracted materials' power frequency ranges from 62 Hz to 80 Hz, with 80 Hz used for mechanical energy extraction.The COMSOL 6.3 Multiphysics program was used as a simulation program.The research studies the association of piezoelectric materials, as well as power car tires, concentrating on their mechanics, electronic components, and thermal properties.The study shows that the pulse electric value is proportional to material thickness, voltage, and strain.Being a function of strain and electric power, the electromotive force, mechanical power, and electric power also change with increasing frequency.The temperature dynamics of piezoelectric mechanisms rely heavily on the resistance of the material, which results in a temperature rise that, in turn, produces an input voltage and electron movement.The 1e9 ohm resistance is the best choice, as it provides increased current flow and an electrical potential of 0.7 volts.
