基于Mathematica的宝塔菜收获机二阶平面铲倾角的优化设计
Optimization of the angle of artichoke harvester's second-order fiat shovel based on mathematica
摘要
Abstract
In order to further improve Chinese artichoke harvester's second-order flat shovel,a multi-objective optimization model of second-order flat shovel was established.A soil breaking model and a resistance model of digging shovel were introduced in this model.With the help of the concept of virtual angle and Mathematica,the model was established with the first-order plane angle being 20.44°,the second-order plane angle being 43.64°,the first-order plane height being 0.12 m,and the virtual plane angle being 30.53°.This theoretically digging shovel model had the minimum force and the maximal effective soil shear.Comparison and analysis of the two second-order shovel from the perspective of theory and software simulation were made.The results showed that the shovel length,digging resistance,the maximum deformation,and stain of optimized digging shovel were decreasing,which indicated this optimal design was satisfactory.This optimal model provided a theoretical support and enlightenment for the design of digging shovel with high soil-breaking ability.关键词
