Abstract

The energy generated by the vibrations that occur in the suspension of a vehicle is often wasted and not properly utilized. If the vibrations on this suspension are utilized optimally, it can serve as an energy harvesting tool for vehicles. In this thesis, a study on energy harvesting tools is made to identify tools that have suitability for use in car vehicle suspension systems. There are several types of energy harvesting identified such as photovoltaic, electromagnetic, electrostatic, radio frequency, piezoelectric, thermoelectric and pyroelectric. All of these tools have the advantage of converting artificial energy into energy for storage. In realizing the study of this thesis, piezoelectric energy harvesting tools become the choice to be studied, because these tools can be utilized and used to harvest the energy resulting from suspension vibrations. In addition, introduction of engineering drawing systems used in methodology such as research design, conceptual design, embodiment design, detail design and detail drawing to obtain quality results and achieve the desired standards. In this methodology also, is told how to find the sketch and the final design of the product to be tested try on the car suspension. As a result of using this system, the result is the final design, the overall cost of the product, the test preparation of the product and the formula that will be used to find the value and energy obtained. Next, the prototype manufacturing process uses plastic materials and 3D printing Ender Pro 3 as the manufacturing machine. A further description of the prototype fabrication process is described in the fabrication and results section. The prototype is produced using the actual measurements of the project and through this prototype, will be tested to obtain the voltage and current values. The test process is used a stroke suspension measure. In this case, the value of the stroke suspension obtained is 100 mm and with this result, will be divided into 5 groups namely 0 mm stroke, 25 mm stroke, 50 mm stroke, 75 mm stroke, and 100 mm stroke. Each group will produce 10 outcomes to get more accurate and quality results. Results will be translated in the form of tables and graphs. If reference is made to the energy harvesting results, it can be concluded that the pressure applied to the piezoelectric sensor affects the increase in voltage and current obtained. As a result of the discovery of voltage and current values in each group, energy values can be obtained and recorded. From the energy value obtained, a calculation of the time required for a car battery to be fully charged from 0v to 12v has been obtained. Lastly, recommendations for improvement are discussed to maximize the results in future.
