Based on a large literature and with the help of some typical examples, the authors show that in many situations it is better to use the various virtual work principles for multibody problems. The Lagrange equations have several disadvantages when they are used for a multibody computer program (time consuming, difficult to accomplish without error a.s ...

Nonholonomic Multibody Dynamics
Multibody System Dynamics, 2003In the first part of the article the authors discuss some ideas for developing a unified geometric basis for modeling, simulation and control of nonholonomic multibody systems. In classical tensor notation they describe the setting up of equations of motion for multibody systems, the inclusion of constraints and the relation between nonholonomy and ...

This chapter includes the main components necessary to formulate the dynamics of planar multibody systems. In this process, the fundamental issues associated with embryogenesis of multibody systems are presented. The main types of coordinates utilized in the formulations of general planar multibody systems are described.

Approximate Bayesian multibody tracking
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2006Visual tracking of multiple targets is a challenging problem, especially when efficiency is an issue. Occlusions, if not properly handled, are a major source of failure. Solutions supporting principled occlusion reasoning have been proposed but are yet unpractical for online applications. This paper presents a new solution which effectively manages the

Orthopedic biomechanics: multibody analysis
2022Joints of the musculoskeletal apparatus are characterized by high complexity, being described by three-dimensional kinematics, which results from the concurrence of translational and rotational motions among the articulating bones forming the joint. The complexity of the kinematics derives from the interaction of different anatomical structures, and ...

Multibody dynamics in acoustophoresis
The Journal of the Acoustical Society of America, 2017Determining the trajectories of multiple acoustically and hydrodynamically interacting as well as colliding particles is one of the challenges in numerical acoustophoresis. Although the acoustic forces between multiple small spherical particles can be obtained analytically, previous research did not address the particle-particle contacts in a rigorous ...

AbstractMulti Body Systems (MBS) consist of a finite number of interconnected elastic and/or rigid bodies. If its number of d.o.f. varies due to contact it is advantageous to calculate dynamics in terms of subsystems. Partitioning into subsystems is fluent but at least reasonable at points of possible contact.

MULTIBODY MODEL OF HIP DISLOCATION
Journal of Biomechanics, 2008Hip dislocation is still a relevant clinical issue of hip arthroplasty [Stralen et al. 2003, Berry et al. 2004]. The factors which play an influence on the propensity for dislocation are related to the patient's anamnesis and to the surgical interview: for example, the acetabular position and orientation, the femoral head size, the neck diameter and ...

Dynamic modeling of parallel manipulators is usually grouped into three main modeling approaches, i.e., the Lagrangian formulation, the Newton–Euler equations and the principle of virtual work. This sections firstly introduced the general modeling procedure and principles of the previous approaches in detail.
