Efficient integration of flexible multibody dynamics
PAMM, 2006AbstractThe modelling of flexible multibody dynamics as finite dimensional Hamiltonian system subject to holonomic constraints constitutes a general framework for a unified treatment of rigid and elastic components. Internal constraints, which are associated with the kinematic assumptions of the underlying continuous theory, as well as external ...

Dynamics of general flexible multibody systems
International Journal for Numerical Methods in Engineering, 1990AbstractA 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 ...

Decoupling Methods in Flexible Multibody Dynamics
13th Computers in Engineering Conference, 1993Abstract The inertia projection schemes used in the existing recursive methods for the dynamic analysis of flexible multibody systems lead to dense coefficient matrices in the acceleration equations. Consequently, there is a strong dynamic coupling between the joint and modal coordinates.

Flexibility in Multibody Dynamics with Applications to Crashworthiness
1994Formulations based on multibody dynamics for the analysis of crashworthiness and impact of vehicles and structural systems are reviewed in this paper. A methodology to incorporate the elastodynamics effects, suitable to describe the elastic deformations of flexible bodies, is discussed.

Forward Dynamics of Flexible Multibody Systems
1994So far, several approaches to the solution of the kinematics and dynamics of multibody systems have been presented. It has been assumed in these approaches that all the bodies satisfy the rigid body condition. A body is assumed to be rigid if any pair of its material points do not present relative displacements.

Experimental Validation of Flexible Multibody Dynamics Beam Formulations
Volume 7B: 9th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2013In this paper, the accuracy of the geometrically exact beam formulation and absolute nodal coordinate formulation are studied by comparing their predictions against experimental data referred to as the “Princeton beam experiment.” The experiment deals with a cantilevered beam experiencing coupled flap, lag, and twist deformations. In the absolute nodal

Motion formalism in flexible multibody dynamics
2017A multibody system is characterized by two distinguishing features: system components undergo finite relative rotations and these components are connected by mechanical joints that impose restrictions on their relative motion. Being able to accurately simulate flexible multibody systems is crutial for predicting dynamic properties of a system.

Flexibility effects in multibody system dynamics
Mechanics Research Communications, 1980During the past f ive years there has been an increasing interest in the development of computer oriented methods for studying the dynamics of multibody systems. A "multibody system" as discussed herein, is defined as an "open-tree" or "open-chain" of connected r igid bodies such that adjacent bodies share at least one common point and such that no ...
