一种平衡能力康复训练台的设计与分析-design and analysis of a balance rehabilitation training platform.docxVIP

摘要摘要在日常生活中,人体的各种动作都必须依靠有效的平衡能力。平衡能力出现问题， 会导致人体站立和行走不稳，容易跌倒，严重者生活无法自理，生活质量下降，对其家 庭及社会造成很大的负担。对于目前社会上许多行动不便的患者，恢复性训练是治疗过 程中极其重要的一个环节，而康复性仪器在其中占有重中之重的地位。用于平衡能力检 测和康复训练的平衡台研究则是目前国内外比较主流的研究方向，它能够客观评价患者 的平衡能力，并配合检测结果调动人体自身的主动性,进行康复训练。本研究主要针对 用于康复训练的平衡台做了以下工作：第一：设计了一种用于平衡能力检测和康复训练的两自由度（2—DOF）平台，平 台采用一种纯转动的并联机构用于平衡能力检测和康复训练，该并联机构可以实现绕 x， y 轴方向的两个旋转运动。对设计的机构进行了运动学和动力学的分析。第二：针对平台的运动，为了能够精确测量平台的运动参数，设计了基于 ADXL345加速度传感器的倾角测量系统，实现了对平衡台旋转运动 x，y 轴方向的倾角测量。 第三：将反映平台 x，y 轴位姿变化的数据通过单片机发送到计算机，在计算机中利用 LabVIEW 进行数据处理，开发了具有显示重心位置实时偏移的界面，为进一步实 现重心位置实时调节，实现康复训练奠定基础。本装置可以实时对人体重心实施扰动，调动人体自身的平衡调节机制，提高了对康 复训练的针对性和灵活性。由于采用了基于 MEMS 的加速度传感器，简化了外围电路 的设计，电路更加稳定准确，也降低了成本，对于促进康复训练仪器的普及有重要的意 义。关键词人体平衡康复训练重心平衡台ADXL345IAbstractAbstractVarious actions are dependent on effective balance ability in daily life. Balance disorders, which causing a great burden on their families and society, serious decline in quality of life, are showed as standing or walking instability, prone to fall. And the patient cannot take care of themselves in daily life. For the patients in the community who has problem of the actions, Recovery training is extremely important during the treatment, rehabilitation equipment plays a most important role. Balance platform which used for balance testing and rehabilitation training at home and abroad is a mainstream research. It can evaluated the patients ability ofbalance objectively, and use the results for patient own rehabilitation training，This researchdid the following work using for this balance platform which used human body balance ability rehabilitation.First, balance platform which used for balance testing and rehabilitation training has been designed. It is a parallel mechanism has two degrees of freedom (2-DOF). It has been used a pure rotational parallel mechanism. The parallel mechanism can be achieved rotating around the x, y-axis directions. And kinematics and dynamics Analysis are done.Second, for platform movement, in order to accurately measure the motion parameters of t
