| Abstract: | Based on Dieter Ammon coherent coefficient model, the feasibility of coherence function model is proved by the measured road signal, the transfer function between the left and right wheel input is got by using genetic algorithm, and the 4-wheel random road input model is built. In the end, the generated pavement power spectral density is verified, which shows that the road file satisfies the relevant requirements. |
