Abstract: |
Based on the analysis of working performances of the precision drill, and the teston the seed release performance of blowing-type metering device, the ma jor factors affectingthe seed release performance and the working scope are obtained. By means of optimumexperiment design, the mathematical models of the major factors are obtained. The effects ofeach factor are analysed to find the optimum working condition fitting the requirments ofseed release performance. |
