Abstract
Aiming at the problem that the traditional cervical traction rehabilitation mechanism only realizes the upright traction, but can't meet the variable angle traction rehabilitation. In this paper, a cervical traction rehabilitation mechanism based on 3-SPR is proposed. The designed cervical traction mechanism can complete four training modes of cervical traction, flexion/extension, left/right flexion and rotation, and realize variable angle rehabilitation exercise. Firstly, the configuration synthesis and degree of freedom of 3-SPR cervical traction rehabilitation mechanism are analyzed according to the single open chain-orientation feature set, which can realize three-rotation and traction rehabilitation. Secondly, the kinematics of cervical spine mechanism is explored, and its inverse position solution is analyzed based on coordinate transformation matrix. Finally, Adams software is used to simulate and analyze the cervical traction rehabilitation mechanism of 3-SPR parallel mechanism to verify the feasibility of the mechanism. The results show that the mechanism moves smoothly, the traction process is safe, and good traction rehabilitation effect can be achieved.
