Flexibility Effects in Multibody Systems
1994This paper summarizes procedures for studying flexible multibody systems using finite segment modelling. In these procedures flexible members of multibody systems are themselves modelled as multibody (or “lumped”) systems. The flexibility is then modelled by springs and dampers between the bodies.

Pulse control of flexible multibody systems
Computers & Structures, 1986An 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.

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.

Flexible multibody systems: preliminaries
2010Multibody 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 ...

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 ...

Flexible Bodies in Multibody Systems
1998The 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.

Flexible Multibody Model of Desmodromic Timing System#
Mechanics Based Design of Structures and Machines, 2009Abstract In the present study, the authors performed a dynamic analysis of the desmodromic timing system, where the valve lifter is realized by conjugate cams, using a methodology of modal synthesis to examine the effects of the deformability of the principal parts, and evaluating the deformations and vibrations of the components under various ...

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 ...
