鼠道犁扰动土壤随机过程研究

    The Study on the Random Process of the Turbulence of Soil Produced by a Mole Plough

      摘要
    • 摘要: 通过田间测试鼠道犁的动态随机牵引力，计算了平均牵引力、动态随机力的傅里叶变换和功率谱密度函数，研究了牵引力周期性变化与土壤扰动破坏之间的关系。

       

      Abstract: The average force,FFT and power spectral density of traction force of a mole plough have been calculated after field test.The relation between the periodical change of traction force and soil fracture produced by the mole plough is also discussed in this paper.
