- Abstract
- Automobile technology is continuously developing, and tire, which is an important part of it, is also being developed as an intelligent component. Tires are components that have a great impact on driving performance and safety, and it is imperative to install a TPMS (tire pressure sensing system) to inform the driver of the condition of the tires while driving. Currently used TPMS uses a battery and periodic replacement is necessary, and various methods to replace it are being studied. Currently, widely studied methods are energy harvesting technology that uses vibration of structures to produce electric energy, and it can be divided into electrostatic power generation, electromagnetic power generation and piezoelectric power generation. In this study, piezoelectric energy power generation method which converts kinetic energy into electrical energy is studied. A device for attaching to a tire rim was devised and the analysis was performed by modeling a double - layer C - shape cantilever beam structure in the form of a free - end cantilever beam in the direction of the center of rotation. Euler-Bernoulli beam theory and Rayleigh-Ritz method were used to derive system equations of motion. Generally, the larger the vibration of the structure, the more favorable the energy harvesting. Therefore, in this study, it is devised to make the resonance frequency of the structure resonate effectively with the frequency, so that the vibration is increased.
