Vibration Measurement And Analysis Of Knee-Ankle-Foot Orthosis (Kafo) Plastic-Metal Type

Abstract

The aim of present paper is to measure the stresses that results from vibration for knee-Ankle-Foot-orthosis (KAFO) at different position during dress up by patient by measuring of accelerometer of (KAFO).Also the pressure between leg and knee -Ankle-Foot-orthosis was measured by using piezoelectric sensor. Total stresses result from applied pressure and acceleration on the KAFO numerically calculated with ANSYS 14 package. The results showed that the values of stresses at the upper KAFO (thigh) are greater than the lower KAFO(shank).this is certainly because of the values of pressure in the upper leg (thigh muscles)are higher than the pressure in shank muscles.
