doi:10.3901/JME.2020.11.072

Abstract

Abstract: A new 1R human knee model which is based on a variable axis rotation, the method of configuration synthesis of bio-fusion knee rehabilitation machanism with automatic alignment of knee joint and exoskeleton axis are proposed, then a series of bio-fusion knee rehabilitation mechanisms are summarized. There is an effective way that a motion compensatary condition for the automatic alignment of the axis of knee joint and exoskeleton joint, and constructs the basic model of the bio-fusion knee joint rehabilitation mechanism, which is based on the spiral theory. Treating the bio-fusion knee joint rehabilitation mechanism as the research object, the freedom of the bio-fusion knee joint rehabilitation mechanism is analyzed with the improved G-K formula, and the kinematics simulation software is used the accuracy of motion compensation is verified by the simulation results, and then the rationality of mechanism synthesis is determined, which provides a new idea for the design method of configuration synthesis of bio-fusion knee joint rehabilitation machanism.

Key words: bio-fusion, rehabilitation of keen joint, spiral theory, motion compensation, type synthesis, rehabilitation mechanism
