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.

Sensivity Analysis of Flexible Multibody Systems

Volume 6: 5th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C, 2005
In this work a general formulation for the computation of the first order analytical sensitivities based on the direct method is presented. The direct method for sensitivity calculation is obtained by differentiating the equations that define the response of the flexible system with respect to the design variables.

Flexible multibody systems: preliminaries

2010
Multibody systems are characterized by two distinguishing features: system components undergo finite relative rotations and these components are connected by mechanical joints that impose restrictions on their relative motion. Broadly speaking, multibody systems can be divided into three categories, rigid multibody systems, linearly elastic multibody ...

Flexible Bodies in Multibody Systems

1998
The motion of flexible bodies in multibody systems can be represented in many applications as a superposition of a large reference motion and small deformations, which allows linearisation in the deformation variables. The linearisation procedure requires a careful analysis of geometric stiffening.

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.

Optimization of Flexible Multibody Systems

2009
The 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.

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 ...

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 ...

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.
