Determining with accuracy, the internal efforts in the human body is a great challenge in Biomechanics, particularly in Physical Therapy and Ergonomics. In this context, the present study develops a human body model that permits a non-invasive determ

This paper presents some results on the modeling and the parameter estimation of the human knee joint. Based on the geometric characteristics of the femur condyle and the tibia plateau, a part of femoro-tibial joint model includes an involute-on-plan

This paper presents some results on the modelling and the corresponding parameter estimation of the human shoulder. This system consists of the clavicle, the scapula, the humerus and the various joints between these bodies and the trunk through the s

This paper presents a simplified dynamical model for the control of one-degree-of-freedom synovial joints considered as pure trochlean joints. This model considers the joint dynamics, the dynamics of the corresponding muscles and their calcium balanc

The aim of the paper is to produce the equations of motion of a multibody system in symbolic form. The formulation permits emphasis of the linearity of the equation with respect to barycentric parameters. Dynamic and identification models for manipul

It is shown how Sturm's theorem, which provides stability criteria for linear differential equations with complex coefficients, may be used to determine the stability of a class of deformable spacecraft which includes symmetrical dual- and triple-spi

A method for examining the stability of a linear periodic dynamic system with many degrees of freedom is discussed, i.e. a system governed by a set of n-coupled Hill's equations. It is assumed that the periodic terms contain a small parameter e. The

The paper presents the main features of the AUTODYN programme developed in Louvain-La-Neuve. This multi-purpose programme, based on the virtual work principle, can be used for vehicle dynamics as well as in robotics and for other mechanical systems.

Rotational Dynamics of Orbiting Gyrostats ISBN: 9783211811986
The classical libration problem of Lagrange is one forerunner of the analogous problem for the gyrostat. Another is the problem of an orbiting symmetric spinning body ated upon by gravitational torques. The equilibrium orientation of such a body with
