摘要
为满足小型的生态景观水域和人工养殖水域的漂浮垃圾打捞需求,同时考虑打捞装置与生态环境之间的美观性以及协调性,研制了一种小巧灵活,环境适应性强的仿生打捞装置.通过运用仿生学原理和MeArm机械臂基础,创新设计了鹈鹕仿生打捞装置的嘴部下喙开合机构、下喙齿轮齿条杠杆滑槽机构、嘴部喉囊底部投放机构、颈部结构和打捞结构等,并提出一种双摇杆机构的三自由度连杆机械臂,满足了打捞装置对灵活性和承载能力的需求.通过应用Matlab仿真和有限元分析软件对仿生鹈鹕水面漂浮物打捞装置进行了运动范围、结构强度和动力学仿真分析,结果表明该设计的仿生装置结构可靠,同时经样机模型实验验证了设计方案的有效性和可靠性,为后续产品的进一步开发提供了理论和实验依据.
Abstract
In order to meet the salvage needs of small-scale ecological landscape waters and artificial aquaculture waters,this paper introduces a small,flexible,and environmentally adaptable bionic salvage device.By applying the principles of bionics and utilizing the MeArm robotic arm as a foundation,innovative designs have been made to the beak mechanism,neck structure,and salvage structure of the pelican bionic salvage device.A three-degrees-of-freedom linkage robotic arm with a double-rocker mechanism has also been developed,satisfying the demands for flexibility and load-bearing capacity.Through Matlab simulation and finite element analysis,the designed structure has been proven to be reliable.Prototype model experiments have further validated the effectiveness and reliability of the design scheme,which provides a theoretical and experimental basis for the future development of similar products.
