Ride Analysis of Three Wheeled Vehicle Using MATLAB/Simulink

چکیده
A spatial six degree freedom mathematical model of a three wheeled vehicle (TWV) used in Asian countries has been developed using multi body system approach. The model includes suspension and tyre compliance. The model consists of a single sprung mass (vehicle body) connected to three unsprung masses (three wheels) at each corner. The suspensions and tires are modeled as springs and linear damper elements. The model consists of six degrees of freedom because the body has three degrees freedom for bounce, pitch and roll motions and each unsprung mass have bounce motion. Vertical dynamic response of the TWV has been found when the vehicle is moving at 45 kmph on random road surface. Damping ratios and natural frequencies are obtained using Eigen value analysis. Ride analysis has been carried out in the frequency domain by performing the spectrum analysis using MATLAB/Simulink.
