Sensivity Analysis of Flexible Multibody Systems
Volume 6: 5th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C, 2005In 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.

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

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.

Passivity-based control of nonlinear flexible multibody systems
IEEE Transactions on Automatic Control, 1995Summary: Global asymptotic stability of a class of nonlinear multibody flexible space structures under certain dissipative compensation is established. Furthermore, for an important subclass of such systems, the stability is shown to be robust to certain types of actuator and sensor nonlinearities.

Symbolic computations in flexible multibody systems
Nonlinear Dynamics, 1996The need for computer aided engineering in the analysis of machines and mechanisms led to a wide variety of general purpose programs for the dynamical analysis of multibody systems. The use of more lightweight structures and an increasing demand of high-precision mechanisms, such as robots, led to the incorporation of flexible bodies in this ...

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 ...

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 ...

Impact and Bifurcation of Flexible Multibody Systems
Volume 5: 19th Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2003In the paper, the process of loss of stability of multibody systems and structures is analyzed. A novel approach is presented and applied as for the statically loaded spatial systems so for analysis of dynamic response of systems imposed on impact. The analysis is based on solution of the dynamic equations and eigenvalue problem of systems, and of ...
