Analysis on Shape Control of Cotton Picking Machine
The paper analyzes the working process of picking cotton machine and determines the influence of geometric parameters of picking hook teeth on the picking friction of seed cotton through mathematical modeling.In the stage of seed cotton winding,the elastic-plastic friction force between the picking spindle and the seed cotton is analyzed,and the mathematical relationship between the radius of curvature of the cone section of the picking spindle and the friction force between the seed cotton and the picking spindle is established.The stripping is simplified as a cantilever beam to build a mechanical model for determining the mathematical relationship between the section diameter of the lowest strength cone and the geometric parameters of the stripping cone.With ANSYS,finite element analysis on three common base materials is conducted to further define the influence of different materials on the stripping strength and verify the influence of cone curvature radius on the picking friction of seed cotton.The research results lay a theoretical foundation for further shape control and multi-objective optimization design of made-in-China spindles.
