ENERGY MATHEMATICAL MODEL OF A SPRAYER

The research was carried out in order to develop an energy mathematical model of a plant protection unit with trailed sprayer, which makes it possible optimize the parameters and operating modes, taking into account their influence on size loss crop yield. For comparison tendencies changes sprayers established practice, computational experiments were performed using developed model. object study is analogue MTZ-82 tractor, main (mass, engine power, kinematic length, etc.) can be changed, sprayer variable (width, speed, tank volume, drawbar location center mass, profile width support wheel diameter, etc.). optimization criterion composite included sum direct indirect costs during operation unit, lost due deviations from optimal modes sprayer. Incorrect choice leads yield losses, resulting its decrease violation deadline for performing technological protect crops weeds, trampling down part by unit's movers processing, especially if there no possibility turning outside field, soil compaction zone growth development root systems. Computational showed that increase coverage 16 32 m at aggregate speed 12 km/h total 3250 MJ/ha 1692 MJ/ha, 7 km/h, working reduces 1971 MJ/ha. Reducing tire 0.6 0.2 accompanied 2793
