借鉴Dieter Ammon的路面相干函数模型，通过实测的路面信号验证该相干函数模型的可行性，应用遗传算法求解左右轮输入间的传递函数，建立四轮随机路面输入模型。最后对生成路面功率谱密度进行验证，结果表明所构建的路面文件满足相关要求。
藉鑒Dieter Ammon的路麵相榦函數模型，通過實測的路麵信號驗證該相榦函數模型的可行性，應用遺傳算法求解左右輪輸入間的傳遞函數，建立四輪隨機路麵輸入模型。最後對生成路麵功率譜密度進行驗證，結果錶明所構建的路麵文件滿足相關要求。

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 .
