The main goal of this research is to use Simulink to optimise quarter-car semi-active suspension systems employing variable spring configurations. Semi-active suspensions are advanced systems that adjust damping characteristics in real-time to achieve a balance between ride comfort and handling performance. The purpose of this study is to investigate the possibility of improving overall suspension performance by adding a second spring in parallel with the main suspension spring. A precise model of the quarter-car suspension system will be developed using Simulink. The vehicle mass, primary suspension spring, semi-active damper, and extra spring will be all included in the model. The semi-active damper will be controlled by a PID controller. The research includes simulating parallel and series configurations of the additional spring to analyze their effects on suspension behavior. Key aspects under investigation include how these configurations impact ride comfort, handling stability, and the distribution of forces within the suspension system. This research contributes to advancing the understanding of how variable spring configurations can be utilized to optimize semi-active suspension systems, offering insights that may benefit automotive industry in designing more effective and efficient suspension solutions for modern vehicles
