Abstract

The aim of this article is mathematical modelling and investigation of chosen parameters of a small energy harvesting system designed for energy harvesting from car tire mechanical vibrations to provide power supply for various sensors, e.g., in tire pressure monitoring system. The energy harvester consists of three permanent magnets inserted into a tube made from polyamide material. Comsol program has been used to calculate the force between the magnets, the stiffness of the magnetic spring, and the natural frequency of the system. MATLAB program has been used to simulate the movement of the moveable magnet to compare it with the measurements. Finally, the parameters of the mathematical model of the energy harvester were investigated and validated on a specially prepared laboratory test bench.

摘要

本文的目的是对一个小型能量收集系统的选定参数进行数学建模和研究，该系统旨在从汽车轮胎的机械振动中收集能量，为各种传感器（例如轮胎压力监测系统）提供电源。能量收集器由三个插入到聚酰胺材料制成的管中的永磁体组成。使用 Comsol 程序计算了磁铁之间的力、磁弹簧的刚度和系统的固有频率。使用 MATLAB 程序模拟了可动磁铁的运动，并将其与测量结果进行了比较。最后，在专门准备的实验室测试台上研究和验证了能量收集器的数学模型参数。
