    摘要:

    在自制的小土槽試驗(yàn)裝置上,，進(jìn)行了水田驅(qū)動(dòng)葉輪輪葉下土壤流動(dòng)的拍攝和輪葉上土壤反力的測(cè)試。在研究輪葉下土壤流動(dòng)軌跡,、流動(dòng)模式和流動(dòng)區(qū)大小變化規(guī)律的基礎(chǔ)上,，分析了輪葉產(chǎn)生的推進(jìn)力和支承力，驅(qū)動(dòng)效率的變化規(guī)律及其與土壤流動(dòng)之間的關(guān)系,。深入分析了有較大陷深和作旋輪線運(yùn)動(dòng)的輪葉的驅(qū)動(dòng)效率較低的原因,。

    Abstract:

    The lug is the basic element of a paddy-field lugged wheel. Soil flowed under the lug develops the pull and lift forces on the lug. In a set of specially designed soil box, the soil flow under the lug was photographed and the soil reaction forces on the lug were measured. Firstly, soil flow track, flow mode and flow zone under a lug were studied. The effects of the pull force, lift force and driving efficiency and their relationship with the soil flow in the interaction between the soil and lug were analyzed. The cause of low driving efficiency was further studied for the lug with slip and deep sinkage. 
