In this paper, we propose a mathematical model for evaluating the performance of an onboard energy harvester. First, the static analysis results using the finite element method and the measurement results using a prototype are compared, and the parameters are supplemented as table data. In addition, the parameters necessary for a mathematical model are identified using a damping vibration. In order to easily evaluate the harvester, we propose a mathematical model that combines the results of using the finite element method with the identified parameters. Finally, a power generation experiment is conducted, and the experimental results are compared with the simulation results to discuss the validity of the proposed mathematical model.
