Effect of Rotational Mass Radius as Energy Storage on a Flywheel (Conceptual Stage)

Abstract

This project focuses on the design and development of a small-scale dynamometer test rig integrated with a variable mass flywheel for motorcycle applications. The main objective is to study how mass distribution effects on rotational speed, input voltage, and acceleration time in order to improve energy efficiency and engine performance. The system consists of a 24 V DC motor, a rotating disc mounted on a shaft, and an adjustable flywheel that allows mass to be positioned at different radial distances. Rotational speed is measured using a tachometer, while acceleration time and input voltage are recorded under different load and test conditions. By changing the radial position of the load and the target speed, the effect of mass distribution on moment of inertia can be evaluated. The dynamic behaviour of the system is analysed based on the relationship between acceleration time and applied voltage. Experimental results show that changes in mass distribution significantly influence acceleration response and overall system behaviour. The prototype provides a simple and controlled platform to study rotational energy characteristics before final flywheel design. Overall, this study supports the development of low-cost and efficient variable mass flywheel systems for better energy use and improved drivetrain performance.
