Simulation Analysis Of Variable Fertilizer Applicator Apparatus Fat Process Based On Discrete Element Method

Crop fertilizer in our country at present mostly adopts the homogenization of fertilizing, fertilizer use efficiency is low, the microelement such as nitrogen and phosphorus potassium usage ratio, loss of fertilizers in the waste of resources but also caused great pollution to the environment According to the regional soil characteristics of various nutrients in soil characteristics and the distribution of crops production, according to the agronomic requirements of the precision machinery into according to the requirements of variable rate fertilization fertilizer, enable farmers to obtain maximum economic benefits and environmental benefits, research for basal fertilizer of cotton seed manure variable technology and equipment has extensive application prospect and important practical significanceBased on the research at home and abroad on the basis of present situation of the technology of variable rate fertilization, the requirement of the discrete element method analysis and calculation, through to the fertilizer particle physics mechanics performance test and analysis, get the 3 d grain size of the fertilizer particle density, moisture content of the stiffness coefficient of the fertilizer particle collision parameters such as coefficient of restitution, and the relationship between its influence factors is givenExpounds the basic principle of discrete element method to solve, the use of the development of integrated analysis and design software based on the discrete element method, the working process of the external tank wheeled distributing device simulation analysis, based on the rigidity coefficient of friction coefficient on the working process of the distributing and the ability of distributing simulation, proved that the discrete element method analysis the fertilizer particle associated with agricultural equipment mechanical parts contact effect, the feasibility of the established grain materials and related mechanical parts of the discrete element method analysis model and the development of the availability of integrated analysis and design software and the discrete element method analysis the rationality of the calculation parameters selection, for complex structure and movement mode mechanical components of the discrete element method simulation analysis laid a foundation...
