用加速度法测量特殊路面的路面谱

提出了一种测取履带式车辆所经的碎石地、硬土地、耕地等特殊路面的路面功率谱的方法。在负重轮轮轴处安装加速度传感器,通过测量该处的时域加速度来间接计算路面功率谱,大大简化了操作过程。并且给出了在碎石地、硬土地、耕地路面上的具体测试结果,验证了方法的可行性和可靠性。

Measurement of Typical Road Surface Spectral by Using Acceleration

A method is introduced to measure the power spectrum of typical road surface such as,the gravel, hard-land and farmland and so on,which tracked vehicles usually travel on.Fixing the acceleration sensor in the axis of the wheel,by measuring the acceleration of the axe to calculate road power spectral indirectly,this greatly simplifies the operation process.And it is certified that the method is feasible and reliable by surface specific test results of farmland,the gravel and hard land.
