基于ADAMS的油茶嫁接机关键结构设计与仿真
Design and Simulation of Key Structure of Camellia Oleifera Grafting Machine Based on ADAMS
摘要
Abstract
The disadvantages of Camellia oleifera grafting machine are expensive,having complex structure and numerous grafting actions.In order to realize the basic function of grafting machine,based on the cleft grafting method,the key structures of the grafting machine such as clamping,handling,cutting and straightening were designed and modeled.At the same time,multiple functional components were reasonably integrated together to ensure the compact structure.In or-der to ensure the rationality and stability of the gripper in the gripping and handling.Camellia oleifera seedlings were taken as reference objects.The axial and radial compressive stress-displacement tests were carried out to obtain mechani-cal curves with different diameters,and the axial and radial ultimate failure loads were 6.71 MPa and 4.14 MPa,re-spectively.The dynamic simulation model of gripper handling mechanism was established with SolidWorks 2021.ADAMS software was used to simulate the dynamics of the handling mechanism and the end-effector composed of the clamping mechanism and the cutting mechanism.The change of the velocity at the center of mass of grafted panicle under different clamping forces was analyzed.The gripper holding force suitable for the structural design of grafting machine and the gripper holding force when the grafted spike was released from the gripper were obtained.The simulation results showed that:the minimum stable clamping force applicable to the clamping handling condition of the grafting machine was 3.8 N.The camellia grafting seedlings would break away from the claw when the clamping force of the claw was less than 0.5 N.The key structure design of grafting machine was reasonable,it can meet the clamping and handling needs in grafting and provide theoretical basis and research ideas for the optimization design of grafting machines and graft-related equipment.关键词
