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 ...

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 ...

Dynamics of Constrained Multibody Systems
Journal of Applied Mechanics, 1984A new automated procedure for obtaining and solving the governing equations of motion of constrained multibody systems is presented. The procedure is applicable when the constraints are either (a) geometrical (for example, “closed-loops”) or (b) kinematical (for example, specified motion).

The idea of complementarity in multibody dynamics
Archive of Applied Mechanics, 2001Abstract Considered in a straightforward manner multibody systems with many multiple unilateral contacts involve a combinatorial problem of huge dimensions, which can only be solved reasonably by the introduction of the complementarity idea.

The Structure of Multibody Dynamics Equations
Journal of Guidance and Control, 1978Several alternative formulations for the dynamics of multibody systems are described. These alternatives include momentum and velocity formulations with decoupling or coupling of constraints. The presentation of equations is facilitated by the introduction of a path matrix and a reference matrix that describe the topology of the H-body configurations ...

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.

Fundamental Concepts in Multibody Dynamics
2015In this chapter, the fundamental ingredients related to formulation of the equations of motion for multibody systems are described. In particular, aspects such as degrees of freedom, types of coordinates, basic kinematics joints and types of analysis in multibody systems are briefly characterized. Illustrative examples of application are also presented

DYNAMICS OF MULTIBODY SYSTEMS – A BRIEF REVIEW
Acta Astronautica, 1989Abstract The subject of multibody dynamics is the simulation of large motions of complex systems of bodies interconnected by kinematical joints and by force elements such as springs, dampers and actuators. Typical technical multibody systems are vehicles, spacecraft, robots, mechanisms of all kinds, biomechanical systems and others.
