摘要

摘要: 为了提高机场跑道摩擦因数测试车的测量精度, 对机场跑道路面不平度和摩擦因数测试车进行了建模和仿真。利用路面功率谱密度和离散Fourier逆变换法建立了机场跑道路面不平度模型作为测量系统的输入激励, 采用阻抗框图建模法, 建立了机场跑道摩擦因数测试车悬挂系统和测试系统模型, 并在该模型的基础上进行了系统仿真, 并将仿真结果与现有机场跑道摩擦因数测试车实测数据进行对比。对比结果表明: 通过对机场跑道摩擦因数测试车进行综合阻抗框图建模, 可将最大相对测量误差从15.7%降低到8.6%, 因此, 建立的数学模型测量精度高。

Abstract: 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.
