Add-on energy harvesting system using cantilever beam in an engine mount

A conventional diesel engine usually has a larger amplitude of vibration compared other engines. Vibration energy in the diesel engine, which usually dissipates into heat and sound, can be utilized as a source of electric power. In this study, the energy harvester consists of a cantilever beam, a pi...

Description
Summary:A conventional diesel engine usually has a larger amplitude of vibration compared other engines. Vibration energy in the diesel engine, which usually dissipates into heat and sound, can be utilized as a source of electric power. In this study, the energy harvester consists of a cantilever beam, a piezoelectric motor, a series of diode bridges, a USB step up and a USB safety tester. In order to conduct the parametric study, the thickness of the cantilever beam varies in the range of 0.1, 0.2, 0.3, 0.4 and 0.5 mm. The experimental test is carried out and measured with an accelerometer, a vibration meter, an oscilloscope and a voltmeter. The result shows that the highest voltage and power can be achieved by setting the thickness of 0.1 mm, which can produce of 4.46 V and 15 mW in the range of 750-1250 RPM.
