Simulation of Wheels in Nonlinear, Flexible Multibody Systems
Multibody System Dynamics, 2002The 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.

Vibrations analysis of flexible multibody systems
Dynamics and Stability of Systems, 1991This paper is the continuation of a previous work (Pascal, 1988a) in which we consider the dynamical analysis of flexible space vehicles modelled by a chain of rigid and elastic bodies with tree structure. The multibody system consists of n + 1 bodies (S$iiei:) (i = 0, 1,…n) interconnected by n hinges la (a = 1,…n). The only external forces and torques

System-Level Modal Representation of Flexible Multibody Systems
Volume 4: 7th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B and C, 2009The presence of both differential and algebraic equations in the model equations, as well as the number of degrees of freedom needed to accurately represent flexibility, prohibit fast simulation of flexible multibody systems (e.g. real-time). In this research, Global Modal Parametrization, a model reduction technique for flexible multibody systems is ...

Optimization of Flexible Multibody Systems
2009The 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.

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 ...

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.

The Motion Formalism for Flexible Multibody Systems
Journal of Computational and Nonlinear Dynamics, 2018Abstract 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 ...

Flexible Bodies in Multibody System Codes
Vehicle System Dynamics, 1998SUMMARY Multibody codes are'efficient tools to simulate nonlinear dynamic behaviour of rigid and flexible multibody systems undergoing large overall motions overlaid by small elastic deformation. This paper gives an overview of common approaches for the equations of motion of flexible body models and presents a general way to prepare the required data ...

New Component Modes for Flexible Multibody Systems
Volume 1A: 16th Biennial Conference on Mechanical Vibration and Noise, 1997Abstract In multibody systems, the deformation of a flexible body is generally modelled by a weighted summation of previously chosen deformation modes. Mode sets composed of static and vibration modes, which proved efficient in structural analysis, are commonly used in practice.
