Abstract

Obtaining a mathematical model for the passive and active suspension systems for the entire automobile model is the objective of this project. Current automotive suspension systems exclusively use fixed-rate springs and damping coefficients as passive components. Vehicle suspension systems are frequently judged on their capacity to enhance passenger comfort and offer acceptable road handling. Only passive suspensions provide a solution to these two conflicting criteria. By directly manipulating the suspensions force actuators, the active suspension has the potential to minimize the traditional design as a compromise between handling and comfort. In this thesis, the active suspension system for a half-vehicle model was constructed using the FUZZY Controller approach. Various types of road profiles are used to compare passive and active suspension systems. In time domain evaluations using sinusoidal road input, the passive and active suspension systems are compared. Results reveal that passenger bounce, passenger acceleration, and tyre displacement decreased by 74.2%, 88.72%, and 28.5%, respectively. This suggests that an active suspension system has a greater chance of improving comfort and road holding.
