ABSTRACT
Assistive devices have been studied in the senses of the universal design and a possible simplification for mass production, and such a concept can be extended to the personalization by using advanced 3D printing technologies, which allows to provide suitable exoskeleton-type devices to fit for the subject’s body to achieve symptom relief. A systematic analytical mechanics is highly important for the investigation of proposed integrative systems and multibody dynamics and its computer simulation enhance the capability to find potential problems in design, for example risky postures for the subject. We introduced multibody dynamics to analyze a knee support exoskeleton by using a linkage system newly designed as a simplification of the device. In the computer experiment, a singular posture was successfully found as the limitation of the device to move safely for subjects having joint dysfunctions
Keywords: Knee support, Exoskeleton-type assistive device, Multibody dynamics (MBD), Joint dysfunction
