Non-linear dynamics of flexible multibody systems
Computers & Structures, 2003Abstract In this work we set to examine several important issues pertinent to currently very active research area of the finite element modeling of flexible multibody system dynamics. To that end, we first briefly introduce three different model problems in non-linear dynamics of flexible 3D solid, a rigid body and 3D geometrically exact beam, which ...

Timoshenko beams and flexible multibody system dynamics
Journal of Sound and Vibration, 1987A method for the dynamic analysis of flexible multibody systems that accounts for rotary inertia and shear deformation effects is presented. Flexible components in the system are discretized by using the finite element method. Because of the large rotations of the system components, a set of reference co-ordinates are employed to describe the motion of

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 ...

Dynamics of flexible multibody systems with tree topologies
Acta Mechanica Sinica, 1992Summary: The dynamic equations of flexible multibody systems with tree topological configuration are derived by using the Jourdain's principle. The independent joint coordinates are introduced to describe the large displacements of the bodies, and the modal coordinates are used to describe small deformations of flexible bodies based on the consistent ...

On the Dynamics and Control of Flexible Multibody Systems with Closed Loops
The International Journal of Robotics Research, 2000The motion control problem for cooperating flexible robot arms manipulating a large rigid payload is considered. An output that depends on the payload position and contributions from the joint motion of each arm is constructed whose rate yields the passivity property with respect to a special input.

Use of Plasticity Theory in Flexible Multibody System Dynamics
Volume 5: 19th Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2003The objective of this investigation is to develop a general nonlinear finite deformation formulation for the elastic-plastic analysis of flexible multibody systems. The Lagrangian plasticity theory based on J2 flow theory is used to account for the effect of plasticity in flexible multibody dynamics.

Dynamical Analysis of a Flexible Multibody System: Lagrangian Approach
Volume 3: Dynamic Systems and Controls, Symposium on Design and Analysis of Advanced Structures, and Tribology, 2006This work presents the dynamical modelling of a flying multibody system. We consider a quadrirotor Helicopter composed of flexible and rigid components. We use the Lagrangian approach to define the equations governing the motion. Deformation modes are used to represent elastic deformation of the substructure relative to a body reference frame.

Nonlinear Dynamics of Rigid and Flexible Multibody Systems
Mechanics of Structures and Machines, 1999Abstract In the present paper a unified numerical approach for dynamics modeling of multibody systems with rigid and flexible bodies is suggested. The dynamic equations are second order ordinary differential equations (without constraints) with respect to a minimal set of generalized coordinates that describe the parameters of gross ...

Truth Models for Articulating Flexible Multibody Dynamic Systems
Journal of Guidance, Control, and Dynamics, 2000Closed-form solutions are developed for the small elastic motions of planar, e exible, multilink systems arranged in chain topologies, in which the links are represented as Euler ‐Bernoulli bars in transverse vibration. The links are connected by pin joints, thereferencearticulation anglebetween adjacent links can bearbitrarily selected, and the system
