This paper has introduced the principle and method of the simulated test on equivalent pavement roughnessspectrum, and roughly analysed the experiment results and their errors.
本文介绍了汽车等效路面谱模拟试验的原理和方法，并对模拟试验结果及其误差进行了初步分析。
2
It analyzed main factors of arising spectrum analysis error which including specimen decarburization layer depth, surface roughness, describing, etc.
分析了引起光谱分析误差的主要因素，如试样脱碳层深度、表面粗糙度、描迹等。

Vibration response signals of vehicle are processed with wavelet analysis to reduce noise efficiently, and road surface roughness is analyzed by road response spectrum.
