轮式拖拉机理论牵引特性计算与验证

Calculation and Verification of Theoretical Traction Characteristics of Wheeled Tractors

对拖拉机某挡发挥的牵引功率、牵引力、比油耗进行计算方法和计算过程的理论研究,对比某型号拖拉机实测的牵引指标,得出所用的方法与原理及计算结果与实测值误差较小,有一定的指导与应用价值。该方法可用于开发新机型时对牵引性能指标提前进行评估与预测。

Comparing the theoretical research on the calculation method and calculation process of traction power,traction force and specific fuel consumption of a tractor and the analysis,and its measured traction index,it is found that the calculated result and the measured value have little difference,so the theoretical research has certain guiding and application value,it can be used to evaluate and predict the traction performance index in advance when enterprises developing new products.
