A RESIDUAL FLEXIBILITY APPROACH TO MULTIBODY DYNAMICS
34th Structures, Structural Dynamics and Materials Conference, 1993Many complex systems can be modeled as a collection of interacting bodies, where the relative motion of the bodies may be large. The dynamics of such systems are simulated using multibody dynamic formulations. Many of these treat each body as a rigid component, but recently the flexibility of the components has been incorporated.

Flexible multibody systems contain both rigid and elastic components and aim at applications such as lightweight and high-precision mechanical systems where the elasticity of certain bodies needs to be taken into account. Since elastic bodies are governed by PDEs, as described in the previous chapter, and rigid bodies by ODEs or DAEs, the mathematical ...

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 ...

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.

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 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 ...

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
