Multibody Dynamics of Very Flexible Damped Systems

Multibody System Dynamics, 1999
The authors consider flexible multibody systems where the bodies may undergo large deformations. Both open and closed loop systems are considered with a variety of connecting joints. Kane's equations are used to obtain the governing dynamical equations. The formulation is then written in algorithmic form and implemented in a numerical procedure (FLXDYN)

Flexibility Effects in Multibody Systems

1994
This paper summarizes procedures for studying flexible multibody systems using finite segment modelling. In these procedures flexible members of multibody systems are themselves modelled as multibody (or “lumped”) systems. The flexibility is then modelled by springs and dampers between the bodies.

Simulation of Wheels in Nonlinear, Flexible Multibody Systems

Multibody System Dynamics, 2002
The authors present the modeling of wheels within the framework of nonlinear flexible multibody systems. The elastic bodies are modeled using the finite element method, and holonomic and nonholonomic constraints among bodies are enforced via Lagrange multipliers.

Sensitivity Analysis of Rigid-Flexible Multibody Systems

Multibody System Dynamics, 1997
To develop an automated design technique, the sensitivity characteristics with respect to the design variables should be calculated. For many practical applications, the flexibility effects must be taken into consideration in order to describe the dynamic behavior of multibody systems involving deformable bodies.

Multibody systems with flexible beams

2003
Flexibility effects in multibody dynamics certainly represent one of the most arduous aspects of the modeling of mechanical systems. There are several reasons for this. First of all, contrary to the rigid case, flexible bodies require both physical and geometrical hypotheses (e.g.: elastic linear behavior, small flexible motion, ...) whose validity ...

Flexible multibody systems-fluid interaction

International Journal for Numerical Methods in Engineering, 1998
We discuss the modelling of a flexible multibody system coupled to a rigid container carrying a fluid with a free surface. Potential flow with modified Rayleigh damping is used to model the fluid. Nonlinear sloshing effects are considered, and no simplifications are made on the field equations and boundary conditions.

Pulse control of flexible multibody systems

Computers & Structures, 1986
An active pulse control method is developed to reduce the vibrations of multibody systems resulting from impact loadings. The pulse, which is a function of system generalized coordinates and velocities, is determined analytically using energy and momentum balance equations of the impacting bodies.

The Motion Formalism for Flexible Multibody Systems

Journal of Computational and Nonlinear Dynamics, 2018
Abstract This paper describes a finite element approach to the analysis of flexible multibody systems. It is based on the motion formalism that (1) uses configuration and motion to describe the kinematics of flexible multibody systems, (2) recognizes that these are members of the special Euclidean group thereby coupling their ...

Dynamics of general flexible multibody systems

International Journal for Numerical Methods in Engineering, 1990
AbstractA general treatment is presented for modelling the dynamics of a flexible multibody system, using a lumped mass finite element approach. The system topology considered here is defined as an arbitrary combination of both rigid and flexible bodies, connected together by joints that permit translation and compliance, in a general tree ...
