In this paper design modification of suspension, spring has been studied. This study has been done on Hero Honda splendor vehicle. In this paper, the performance of the Shock absorber is done by placing a piezoelectric sensor in the strut of the vehicle, and the real-time loads acting on the vehicle is obtained with ARDUINO UNO microprocessor board and is connected to the Display/computer unit to save the load value with respect to time. Continuously monitoring the actual load acting on the components in real-time leads to the determination of the actual range of loads acting on that component in that particular environment, based on which the component can be designed on both materials and structurally for that concern environment which leads to avoiding overestimation of loads and additional weight built up. The vehicle handling becomes very difficult and leads to an uncomfortable ride when bouncing is allowed uncontrolled. Hence, the design of spring in a suspension system is very crucial. The analysis is done by considering bike mass, loads, and no of persons seated on the bike. Creation of structural component done by using design software CATIA, now the values are imported to ANSYS workbench for fatigue analysis to calculate the stress, stress, total deformation for on-road condition.
