Simulation And Experimentation On The Mechanical And Hydraulic System In Virtual Prototype Of Minitype Sugarcane Harvester

Sugar cane is a kind of central economic crop in the south of China. Now, the traditional handcraft harvest mode with high intensity-labors and low productivity is still used in China. However, with wide and flat terrain, some developed countries which produce abundant sugar such as America and Australia, mainly develop large-size sugar cane harvester, which has high mechanization and efficiency; simultaneously has high machine cost. But in south of China, most sugar canes are planted on hill, sloping field, and therefore the large-size sugar cane harvester is not suitable for it. Accordingly, it is important and necessary to develop a small-size sugar cane combining harvester to apply to such field with advanced virtual prototype technique.This paper has mainly researched the hydraul ic and control system in the mini type sugarcane harvester. We set up and s i mu I ate the dynam i cs mode I of the r i se and fa 11 frame w i th the software ADAMS. A new method of mode I i ng and s i mu I at i on , wh i ch doesn't belong to any hydraulic simulation software in being, is used in dynamic figure simulation of the hydraulic system. We build the non-linear simulation model of the general hydraulic component in Mat lab / Simulink which has a powerful mathematical operation capability. In this way, themodularization building and the design of the component parameter in the simulation model of the hydraulic system can come true on the graph and mutual modeling. With the figure sub-module of the hydraulic component, we set up the dynamics simulation hydraulic model of the rise and fall frame, the dynamics simulation hydraulic model of walking system, the dynamics simulation hydraulic model of the holding sugar cane device and the dynamics simulation hydraulic model of the cutting sugar cane device respectively based on the different machine system. Through simulating these models we get the characteristic, and have some important parameter analysed and optimized.On the base of analyzing the characteristics and the interface method of the two engineering software ADAMS and MATLAB, the interface of ADAMS / Controls is redesigned to integrate the hydraulic system model in Simulink and the mechanical system model in ADAMS in order to bui Id the virtual mechanical and hydraulic co-simulation environment of the minitype sugarcane harvester. At last we validate the co-simulation result with the physics experiment.
