摘要
机器人的腕关节对于确定末端执行器的接触状态以及位置和姿势而言具有十分重要的作用,腕关节的性能直接决定了整个机器人手臂性能的优劣。传统的机器手腕关节多是刚性结构,对环境的适应性比较差。腕关节的柔顺性改善及其重要。形状记忆合金,即SMA因其具有温度记忆效应、形状记忆效应、超弹性而广泛应用于航空航天、交通、能源、机械电子、生物、医学及日常生活领域。作为一种新型功能材料,对其的研究已经成为智能材料和结构领域的一项重要研究内容。本文的主要通过对仿生腕关节进行结构分析,结合SMA材料特性,选用合适的SMA材料,设计出一种具有较大运动范围的仿生腕关节的驱动结构。主要内容如下:第1章阐述本文的研究背景和目的。第2章对腕关节结构进行了介绍。第3章介绍了SMA及其特性。第4章对本文采取的驱动结构及相关问题作了介绍。第5章是本次设计的实物图。第6章总结了本文的主要工作、结论,同时对后续工作做出了展望。

Abstract
The wrist of the robot has a very important role in determining the contact state and position and posture of the end effector. The performance of the wrist determines the performance of the whole robot arm directly. The traditional machine wrist joints are mostly rigid structure, the adaptability of the environment is relatively poor. Improvement of the compliance of the wrist and its importance. Shape memory alloy, that is, SMA is widely used in aerospace, transportation, energy, mechanical electronics, biology, medicine and daily life because of its temperature memory effect, shape memory effect and superelasticity. As a new functional material, its research has become an important research content in the field of intelligent materials and structures. In this paper, we mainly through the structural analysis of the bionic wrist joint, combined with the characteristics of SMA material, choose the appropriate SMA material, designed a larger range of motion of the bionic wrist joint drive structure. The main contents are as follows: Chapter 1 elaborates the research background and purpose of this paper. Chapter 2 describes the wrist structure. Chapter 3 introduces SMA and its characteristics. Chapter 4 introduces the driver structure and related problems in this paper. Chapter 5 is the physical map of this design. Chapter 6 summarizes the main work of this paper, the conclusion, while the follow-up work to make a prospect. [资料来源:http://www.doc163.com]
