Prediction of the Effective Spectrum of Soft Terrain Under Driving Wheel

摘要: 应用驱动型的软路面不平度测量仪测量了驱动轮下的有效软路面谱,分析了驱动力、轮胎接地比压、土壤特性对有效谱的影响关系。根据试验结果提出了有效软路面谱的预测计算表达式。经试验验证,该公式的计算值与实测值吻合较好。

Abstract: The authors measured the effective spectrum of soft terrain under a driving wheel by means of the driving measuring equipment for soft terrain roughness. The influence of the factors (such as driving force, unit-pressure on contacting ground and compressivc strength of terrain) on the effective spectrum were analyzed. A prediction equation of the effective spectrum was put forward. Results of the test showed good agreement, with the calculated ones .
