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 ...

DYNAMICS OF FLEXIBLE MULTIBODY MECHANICAL SYSTEMS

Transactions of the Canadian Society for Mechanical Engineering, 1991
In this paper the formulation and simulation of the dynamical equations of multibody mechanical systems comprising of both rigid and flexible-links are accomplished in two steps: in the first step, each link is considered as an unconstrained body and hence, its Euler-Lagrange (EL) equations are derived disregarding the kinematic couplings; in the ...

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.

Flexible multibody systems: preliminaries

2010
Multibody systems are 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. Broadly speaking, multibody systems can be divided into three categories, rigid multibody systems, linearly elastic multibody ...

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 ...

Optimization of Flexible Multibody Systems

2009
The design process of road vehicles, very often based on intuition and experience, can be greatly enhanced through the use of generalized optimization techniques. In a first application, the vehicle optimum design is achieved through the use of an algorithm with finite differences sensitivities.

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 ...

Sensivity Analysis of Flexible Multibody Systems

Volume 6: 5th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C, 2005
In this work a general formulation for the computation of the first order analytical sensitivities based on the direct method is presented. The direct method for sensitivity calculation is obtained by differentiating the equations that define the response of the flexible system with respect to the design variables.
