OPTIMIZATION OF TECHNICAL INDICATORS OF A POTATO HARVESTING MACHINE USING THE METHOD OF MATHEMATICAL PLANNING

In the article from the Centrifugal Lifting Rod Elevator (CLRE) equipped potato backhoe loader worker parameters mathematician planning method using optimization results. The experiments are based on the Hartley-4 plan. Based on held, four incoming factor (drum) rotations number, elastic drum width, elevator speed, worker (of) soil communication rate (Y1, %) and of the nodes damage (Y2, %) impact learned. Obtained second level regression the equations are Fisher and Student criteria based on checked. Optimization as a result of the car high efficiency provider acceptable values detected: drum rotations number of 120 rpm, elevator speed 0.94 m/s, working slot 0.010 m. Field tests as a result soil 81.62% penetration, nodes damage by 5.74% reached. These indicators to the traditional KKS-1.4 combine 10-12% higher than efficiency provides.
