本文在对水田土壤的力学性质进行分析和试验的基础上,对我国水田拖拉机驱动叶轮的工作特性进行了理论分析,导出了予测驱动叶轮沉陷、滚阻、推进力、驱动力以及驱动叶轮效率的理论公式,提出以驱动叶轮效率作为评价驱动叶轮工作特性的综合指标。并对吉林1号叶轮进行理论计算。据此可对不同水田土壤条件下驱动叶轮的工作特性进行理论予测,从而为设计改善叶轮结构、评价叶轮工作特性提供了一定的理论基础。
Based on the analysis and experiment on the mechanical properties of paddy soils, the operating characteristics of paddy-driven tractors in paddy fields in our country are theoretically analyzed. The effects of predicting impeller impedances, roll resistance, propulsion, driving force and driving impeller efficiency The theoretical formula is proposed to drive the efficiency of the impeller as a comprehensive evaluation of the driving impeller characteristics. And Jilin 1 impeller theoretical calculations. Based on this, the working characteristics of driven impellers under different paddy soil conditions can be predicted theoretically, which provides some theoretical basis for designing and improving the structure of the impeller and evaluating the operating characteristics of the impeller.
