Abstract
This work focuses on obtaining the natural frequencies and simulation of dynamic modes of a typical four wheeler SUV suspension spring. A mathematical model of the suspension spring is developed in MATLAB assuming 4 DOF considering half car model of the vehicle. Lagrange's method is used to solve the motion equations and extract the predominant dynamic mode frequencies in MATLAB. Further, Simulink is utilised for validation the results determined in MATLAB by constructing the Power Spectral Density curves of the dynamic response depending on one of the eigenvectors of the suspension system under consideration.
