Orthogonal Experiment Optimization on Air-suction Precision Seed-metering Device
摘要
Abstract
The design of quadratic regression orthogonal rotating experiment was used to test the performance of air-suction precision seed-metering device on the type JPS -12 seed metering performance testing bench. The seeding qualified index was 72.31% -98. 17%. The leaking index was 0.51% ~ 18.7%. The regression equation was received by regression analysis of the test results. 3-D figures were drawn with Matlab. Various effects on the experimental indexes by each factor could be received. The experimental factors were optimized, and then the best combination was achieved. When the relative pressure was -2.86 kPa, the hole diameter was 5.2 mm and the speed of seed tray was 21 r/min, the seeding qualified index was 91. 03% and the leaking seed index was 2. 98% .关键词
