The Kinematics Simulation And Dynamic Analysis And Design Of The Mini-Type Sugarcane Harvester's Uplift

Developing mini-type sugarcane harvester used in hill has great meaning to changes the behind in sugarcane harvester of our country and improves the mechanization application of agriculture, and has the good development opportunity and the potential market. The uplift structure has vital effect to sugarcane's supporting, cutting, feeding and cutting quality. Therefore, Carries out simulation and dynamic analysis and design to the uplift, has considerable meaning to developing mini-type harvester. The paper's main work are the following parts:(1) Based on the research ahead, this paper proposed that a new multi-flexiblevirtual sugarcane model doing the kinematics dynamics simulation. This model is composed of multi flexible short beam, and much closer to the real status. It improves the authenticity of virtual research of sugarcane harvester machine.(2) Based on the virtual research, we had done the indoor simulation test to analysis the factor which influencing the cutting performance of the sugarcane cutter device. Carried out the regression analysis of the indoor simulation test result, This paper established the experience formula of cut loss, broken rate and cut force which was about walk speed, rotate speed of cutter and cutter obliquity. Through analyzing the formula, we obtained the rule of cut loss, broken rate and cutting force which was changing with the walk speed, the rotate speed of cutter and the cutter obliquity, and determined the best operational parameter of sugarcane harvester machine, and determined the actuator frequency of dynamic analysis for the next step.(3) Considered the result of the test, we knew that the vertical direction vibration of uplift device and cutter device is the primary factor of cutting quality. In order to...
