摘要: 本文应用相似理论和模型试验,采用比例缩尺nL=2的模型铲刀,建立树木移植机下铲阻力与土壤状况、铲刀类型和铲刀下铲阻力距离等因素之间的经验公式。试验表明,该经验公式在试验取值范围内具有较高的预测精度。

Abstract: Based on the analysis for a soil-tree transplanter system,a empiric eduation relating the spading resistance of a tree transplanter with state of soil,type of spade and spading distance has been developed by the model spade which scale factor is equal to 0.5.Predicted spading resistance generally is accurate to within 8.95% of actual prototype spade in the range of the test value by the predicting equation.
