| Abstract: | A multiple degree of freedom vibration model is established, which is subjected to multiple support displacement excitations, for trucks equipped with the equilibrium suspension and full driver cab sus?pension. A transient analysis is performed with numerical simulation for the generation of random excitation function in time domain by the pavement. From the analysis, the maximum transient value of dynamic vehicle loads is obtained and compared with the results from power spectral analysis. |
