Simulation and Analysis of the Motion of Paddy Field Stirring Knife Based on MATLAB
摘要
Abstract
In order to further study the motion characteristics of paddy field puddling blades and explore the relationship between factors affecting the quality of puddling blade operations,a motion model of paddy field puddling blades is es-tablished based on actual production conditions.The motion equation of puddling blades is established through theoreti-cal analysis,and formulas for absolute velocity and directional acceleration are given.Using MATLAB(Matrix&Laboratory)software,the orthogonal experimentation of 3 factors and 3 levels was used to depict the motion trajectory of the puddling blade under different operating conditions.Through the graph,it was found that the forward speed mainly affects the lateral span of the motion trajectory,the blade shaft speed mainly affects the number of motion trajectories,and the turning radius mainly affects the longitudinal span of the motion trajectory.Among the 27 graphs,there are 7 non intersecting trochoidal curves.When v=1.5 m/s,ω=180 r/min and R=0.35 m,the trochoidal pattern is obvious and the intersection area is large.When analyzing the speed ratio curve of rotary tillage with a puddling blade,it was found that the blade shaft speed and rotation radius have a positive effect on the rotary tillage speed ratio;The forward speed has a negative impact on the rotary tillage speed ratio.关键词
