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.

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 ...

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 ...

Recursive flexible multibody system dynamics using spatial operators

Journal of Guidance, Control, and Dynamics, 1992
This paper uses spatial operators to develop new spatially recursive dynamics algorithms for flexible multibody systems. The operator description of the dynamics is identical to that for rigid multibody systems.
