  • In order to improve the measure accuracy of frictional coefficient for airport runway, the pavement roughness and frictional coefficient measure vehicle of airport runway were modeled and simulated.The power spectral density of pavement and inverse discrete Fourier transformation were introduced to model runway surface roughness as excitation input.Impedance diagram was used to model the hanging system and measuring system of the measure vehicle.The simulation was processed based on the system models.The validity and feasibility are verified by comparing the simulation results with the measured data of the existing measure vehicle.It is indicated that the maximum relative measure error of frictional coefficient reduces from 15.7% to 8.6%, so the measure accuracy is improved by modeling the measure vehicle with impedance diagram.
