通用旋转设计优化旱地驱动叶轮参数的研究

Quadratic General Rotary Unitized Design Used in the Optimum Configuration Parameter of Iron Wheel with Lugs on Dry Land

利用通用旋转组合试验设计方法,探讨旱地叶轮的使用参数优化问题。采用田间试验,定量地分析了叶片入土角度和入土深度对叶轮滑转率的影响,得到滑转率回归模型。通过对模型的分析表明:在一定牵引负荷下,入土角度和入土深度对驱动叶轮的滑转率有明显的影响,而且叶片入土深度比入土角度对滑转率影响稍大些。通过对模型的统计择优分析,并结合实际使用,得到叶轮在驱动力为1 435N时入土角度和入土深度的优先选用的组合,即入土深度为53mm,入土角度为90°,此时的滑转率为18.98%。

The method of quadratic general rotary unitized design was discussed in detail when it was used for the study of the optimum configuration parameter on the iron wheel with lugs. Based on the field experiment data, regress model on silp and lug angle and lug depth were obtained. By analyzing the regression model, some conclusions were eoncluded：under the certain tractive force, the lug depth＇ s effect on silp is bigger than the lug angle＇ s. Optimum analysis to slip regress model and contact practice was conducted and the results showed the when the drive is 1435N, the first choice lug depth is 53mm and lug angle is 90 degress,the slip is 18.98%.
