【摘要】 通过理论分析和实际路面的测量，阐述了直接在汽车车桥上安装传感器测量路面谱的一种简便方法，并通过与用五轮仪测量路面谱方法的结果对比，得出了此种方法在一般汽车性能试验中的实际应用价值．更多还原

【Abstract】 Based on theoretical analyses and a field survey of road surface, we expound a simple way of installing sensor on axletree directly to measure spectrum of road surface roughness. A comparison with the testing performance by fifth wheel instrument for road surface shows that the new method is practical and effective.更多还原
