Optimization Of High Speed Plow Surface

Abstract: this paper analyses and calculates the plow parameters about two kinds of high speed plows LEMKEN and KUHN, and studys the relation between the geometric parameters of shape of moldboard plow surface and soil properties, plowing quality, forces properties, plowing speed, resistance and energy dissipation during the plowing. Then according to the direction of developing high efficiency and saving-energy agriculture, under the premise of good farming quality this article puts forward a kind of method setting the mathematics model about plow resistance through the new cultivation principle and the new design principle.This paper makes the soil movement be four sections: a) Cutting soil with edge; b)The soil movement along the plowshare and plow chest's below surface; c) The soil movement along the plow cliff ;d)The soil movement beyond the plow in the course of farming in order to study the force of moldboard plow surface.After contrasting and optimizing this paper gets a set of parameters. Then according to these parameters the paper sets up entity model, and after validating and analyzing with finite element it can save time of calculating. On the other hand, it can provide a good method of design of moldboard plow surface.
