Statistics Analysis of the Effective Spectrum of the Soft Terrain Surface

摘要: 本文利用专门研制的软路面不平度测定仪,测量了几种田间软地面的路面谱(原始地表路面谱、车辙谱和有效路面谱),根据试验数据统计出考虑了土壤和轮胎特性影响的有效软路面谱计算表达式。经试验验证,该公式的计算值和实测值吻合较好。

Abstract: The authors have measured the spectrums of the soft terrain surface by the measuring equipment of the soft terrain roughness (spectrum of the original terrain surface, spectrum of rut, spectrum of effective terrain surface), and according to testing results have put forward the relation of the effective spectrum of the soft terrain in consideration of the influence of the soil and the tyres. Results of test have shown that the good agreement is shown by comparing the calculated results with measured ones.
