Investigation of Vibration on Suspension Systems at Different Load and Operating Conditions

A suspension system is an important part of a two wheeler since it reduces the effects of travelling over rough ground, leading to improved ride quality, and increase in comfort due to substantially reduced amplitude of disturbances. Recently, vibration isolation and reduction techniques have become an integral part of machine design/vehicle design and hence the need for accurate measurement and analysis of mechanical vibration has grown. In this study vibration measurement has been carried out in two different suspension systems of two wheelers (nitrox & normal) using accelerometer with Fast Fourier Transforms (FFT) on DEWEsoft software. The amplitude vs time graph for the shock absorbers are measured and analyzed for the two different loads and three road conditions. The result shows that the nitrox suspension system is efficient and gives the best results.
