This work presents the mechanical design of an artificial hand in order to address the need for a commercially feasible prosthetic hand.
The hand has 3 compliant fingers and a thumb attached to a reconfigurable palm. The fingers and palm are a novel design, which is based on the natural arches of the hand. The design is modular, minimizing the number of parts and reducing assembly time.
This hand and the expandable socket are designed for transradial amputees. It has 9 degrees of freedom (DOFs), 2 of them for the reconfigurable palm. The kinematics and adequate excursion for the fingers and palm are illustrated by finite element method (FEM).
The study implements the mechanical parts by using rapid prototyping to assess preliminary results.
本研究旨在设计一款人工手的机械结构，以满足市场上对商业可行的假肢手的需求。
该手具有3个柔顺手指和一个连接到可重构手掌的拇指。手指和手掌采用了基于手部自然拱形的新颖设计。这种设计模块化，减少了零件数量并缩短了组装时间。
这款手和可扩展的接受腔专为经桡骨截肢者设计。它有9个自由度，其中2个用于可重构手掌。通过有限元方法（FEM）展示了手指和手掌的运动学及足够的行程。
本研究通过快速成型实现机械部件，以评估初步结果。
