MODELING AND SIMULATION OF HUMAN LEG USING BOND GRAPG

Abstract

Abstract

The analysis of biomechanical leg is a very important clinical instrument to determine the nature of disease. Now a day many researchers analysed on biomechanics system such as human gait. The modelling and simulation of human gait is developed through various techniques such as vectorial mechanics Lagrange`s equations, Kane method. These dynamic model of human body illustrate a different positional forces which is exerted on a human leg like a muscle, tendon, and other physiological effect. One of the techniques to simulate the human gait is bond graph modelling techniques. This technique avails to develop the model in multi energy domain. The generated differential equation is further used for simulation. . The present work proposed a computational model of human gait through bond graph modeling and simulation work is carried out on Symbols Sonata© software. The fifth order Runga-Kutta method used for iteration. This work also revealed the introduction and different methodologies which used in the analysis of human leg e.g., inverse dynamic simulation and direct dynamic simulation and also explain the cyclic nature of gait.
