The Application of Bond Graph Theory on Automobiles Modeling

摘要

Based on the bond graph theory, the acquisition of state equation of vehicle suspension is presented. Set an example to a five degrees of freedom vehicle suspension model, the simulated results are obtained with the aid of Matlab/Simulink software. Bond graphs are equation based, and are superior to traditional differential equations, they can provide the dynamic digital simulation in time and frequency domain, they can present the static simulation and omit the transition and class-decreasing process which is needed for traditional differential equations.
