Design And Simulation Optimization On Integrated Operating System After Sugarcane Harvest

For research status sugarcane combine harvester and delivery system at home and abroad, and in order to solve the problems of transmission congestion, low stripping the net rate and tail broken rate, the use of virtual design and simulation analysis tools to develop the delivery system methods and techniques about whole-stalk sugarcane combine harvester were researched on. According to the study of conveying mechanism, leaf-stripping mechanism, leaf-peeling mechanism and tail-breaking mechanism, and in order to investigate the effect on the quality of the peeling leaves during leaf-stripping process and the influence of tail-breaking speed on the quality of the tail-breaking quality in test, the main work and conclusions were as follows:The integrated operating system after sugarcane harvest of whole-stalk sugarcane harvester which had front conveying mechanism, two leaf-stripping mechanism, two leaf-peeling mechanism and back conveying tail-breaking mechanism was designed.With the tools of virtual design and simulation analysis, virtual prototype simulation model of the integrated operating system after sugarcane harvest was built, and the mechanism speed parameters for the simulation test of front conveying mechanism, two leaf-stripping mechanism, two leaf-peeling mechanism and back conveying tail-breaking mechanism were optimized.A central composite rotatable orthogonal experimental design was employed. Through the experiment analysis and simulation results, the optimal values of front and back conveying mechanism speed was220r/min, the first leaf-stripping impeller speed was574r/min, the second leaf-stripping impeller speed was383r/min, two leaf-peeling impellers speed were490r/min and tail-breaking wheel speed was184r/min. Correspondingly, the non-net-stripping rate, tail broken rate, skin broken rate and stalk broken rate were5.18%,98%,12.46%and0%, respectively.
