Abstract

The automotive industry has witnessed remarkable advancements in recent years, with a growing emphasis on enhancing vehicle performance, ride comfort, and safety. Traditional passive suspension systems, while effective to a certain extent, exhibit limitations in adapting to varying road conditions and driver preferences. This limitation can impact ride comfort, handling, and vehicle stability, necessitating the exploration of innovative solutions.This study presents a comprehensive investigation into the design and simulation of an active suspension system, leveraging cutting-edge technology to address the shortcomings of conventional passive systems. The proposed system employs a combination of advanced sensors, precision actuators, and intelligent control algorithms to adapt suspension characteristics in real-time.The key components of this research include the meticulous selection of sensors, the design and integration of actuators, and the development of a robust control strategy. Sensors are strategically chosen to gather data on road conditions, vehicle dynamics, and driver inputs. Actuators are engineered to provide precise and rapid adjustments to the suspension system. The control strategy is optimized to ensure seamless coordination between sensors and actuators, thereby enhancing ride comfort, vehicle stability, and safety.Through rigorous simulation using state-of-the-art software tools, the active suspension system’s performance is evaluated across a spectrum of road conditions and driver preferences. The results of these simulations are expected to reveal substantial improvements in ride quality, handling, and overall vehicle performance.This research not only holds the promise of advancing automotive suspension technologies but also carries implications for the broader automotive industry, where improved comfort and safety are paramount. Furthermore, it sets the stage for future developments in active suspension systems and their integration into the vehicles of tomorrow. In conclusion, this project represents a significant step towards achieving a more adaptable and responsive automotive suspension system, with the potential to revolutionize the driving experience. The findings presented herein are poised to contribute to the ongoing evolution of automotive engineering and the pursuit of safer, more comfortable, and efficient vehicles.
