Mechanism design of elbow joint rehabilitation robot

Aiming at the problems of low mechanism precision, large motion inertia, and ease of secondary patient damage in the elbow joint rehabilitation robot, an exoskeleton parallel robot that can realize two degrees of freedom (2-PRR-S) motion of the elbow joint is designed. First, use Solidworks to complete the design and modeling of each component, and use ANSYS to perform finite element analysis on some important components to check the strength of the components. Finally, Adams is used to performing kinematic analysis in order to verify the kinematic properties of the forearm support, and the check analysis of the whole mechanism’s kinematic properties is completed. The simulation results show that the designed elbow joint rehabilitation robot meets the design requirements.
