Energy Generation From Vehicle Suspension

Abstract

With the rapid increase in the number of vehicles worldwide, a significant amount of mechanical energy is continuously dissipated in vehicle suspension systems due to road irregularities such as bumps, potholes, and uneven surfaces. This energy is normally wasted in the form of heat. This paper presents a practical approach for harvesting energy from vehicle suspension systems and converting it into useful electrical energy. The proposed system uses a mechanical rack and pinion mechanism coupled with a DC generator to convert vertical oscillatory motion of the suspension into rotational motion. The generated electrical energy can be stored in a battery and utilized for low-power applications such as vehicle lighting, sensors, or charging electronic devices. The proposed method is economical, environmentally friendly, and suitable for real-time implementation. Experimental analysis indicates that the system can generate usable power without affecting ride comfort significantly.

Introduction

The passage describes a system that harvests otherwise wasted mechanical energy from vehicle suspension movements caused by road bumps and irregular surfaces. Instead of being lost as heat, this vibration energy is converted into electrical energy using a rack-and-pinion mechanism connected to a DC generator.

The generated electricity can be stored in a battery and used for low-power applications such as lighting, sensors, or charging devices. The approach is presented as cost-effective, eco-friendly, and practical for real-world use, with experimental results showing that it can produce usable power without significantly affecting ride comfort.

Conclusion

This paper presented a method for generating electrical energy from vehicle suspension systems using a rack and pinion mechanism. The proposed system effectively converts mechanical vibration energy into usable electrical energy. It offers a sustainable and practical solution for energy harvesting in vehicles. With further optimization, the system can contribute significantly to green energy initiatives in the automotive sector.
