Forward Dynamics of Flexible Multibody Systems

1994
So 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.

Flexibility effects in multibody system dynamics

Mechanics Research Communications, 1980
During 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, 1992
Summary: 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, 2000
The 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, 2003
The 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.

Nonlinear Dynamics of Rigid and Flexible Multibody Systems

Mechanics of Structures and Machines, 1999
Abstract 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 ...

Dynamic analysis of flexible multibody systems

2004
The paper presents numerical solutions for constrained flexible multibody systems. The equation of motion for holonomic constrained flexible system undergoing large displacments and rotations but small elastic strains, using description in terms of finite element coordinates, is derived.

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, 2006
This 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.

Flexible Multibody Dynamic Analysis of the Wiper System for Automotives

Transactions of the Korean Society of Mechanical Engineers A, 2010
This paper presents the dynamic analysis method for estimating the performance of flat-type blades in wiper systems. The blade has nonlinear characteristics since the rubber is a hyper-elastic material. Thus, modal coordinate and absolute nodal coordinate formulations were used to describe the dynamic characteristic of the blade.
