Research On Intelligent The Furl Mechanism For Stubble Machine Of Desert Shrubs

According to the growing environment and growing gesture of shrubs, designing and manufacturing of intelligent shrubs stubble machine is imperative. Furl manipulator is important mechanism and the key component of intelligent shrubs cutter. The performance of the cutter has important effect on the application and development of shrubs resources. The efficiency of the manipulator is an important factor of cutting quality. The work of the furl manipulator is completing to stretch attached to the ground, furling, clamping, tilting the appropriate angle of shrubs with sensor positioning. This will be prepared for the follow-up cutting work. The proposed intelligent furl manipulator changed the cutting way from no supporting way to supporting way, improved the miss cutting and tearing skin phenomenon, enhanced the cutting effect and cutting speed of shrubs. The studies which has important theoretical values on the intelligent of stubble machine.This article use Pro/Engineer to complete the 3D model of manipulator and establish the equation of four degrees of the furl manipulator with the method of D-H. The article also deduces Jacobian Matrix and establish the timing diagram manipulator. Then using finite element analysis software ANSYS for grid partition, we can obtain the stress distribution and deformation figure of the manipulator; finally, the position and posture in work process of the manipulator are verified and the structure statics analysis of the manipulator is completed. Using project analyzing software ADAMS of manipulator proceed on dynamics analysis, determine the manipulator sforce, speed, the relationship between the acceleration and displacement; the simulation analysis in every moment of the manipulator underlie action process. These will provide theoretical basis for the trajectory planning and control theory.
