Nonlinear Dynamics of Rigid and Flexible Multibody Systems
Mechanics of Structures and Machines, 1999Abstract In the present paper a unified numerical approach for dynamics modeling of multibody systems with rigid and flexible bodies is suggested. The dynamic equations are second order ordinary differential equations (without constraints) with respect to a minimal set of generalized coordinates that describe the parameters of gross ...

Dynamics of flexible multibody systems with hybrid uncertain parameters
Mechanism and Machine Theory, 2018Abstract The most popular way to study the dynamics of a multibody system with random parameters is the probabilistic method under the assumption that the mean values and variances of the random parameters are deterministic. For many engineering systems, however, the mean values and variances of those random parameters are inherently interval ...

Open-loop flexibility control in multibody systems dynamics
Mechanism and Machine Theory, 1995In this paper inverse dynamics of flexible multibody systems for the realization of the prescribed motion tasks is formulated. The number of actuators is equal to the dimension of the task space which is usually equal to the rigid body degrees of freedom.

A Variational Approach to Dynamics of Flexible Multibody Systems
Mechanics of Structures and Machines, 1989This paper presents a variational formulation of constrained dynamics of flexible multibody systems, using a vector-variational calculus approach. Body reference frames are used to define global position and orientation of individual bodies in the system, located and oriented by position of its origin and Euler parameters, respectively.

Dynamical Analysis of a Flexible Multibody System: Lagrangian Approach
Volume 3: Dynamic Systems and Controls, Symposium on Design and Analysis of Advanced Structures, and Tribology, 2006This work presents the dynamical modelling of a flying multibody system. We consider a quadrirotor Helicopter composed of flexible and rigid components. We use the Lagrangian approach to define the equations governing the motion. Deformation modes are used to represent elastic deformation of the substructure relative to a body reference frame.

Truth models for articulating flexible multibody dynamics systems. II
Guidance, Navigation, and Control Conference, 1997Closed-form solutions are developed in this paper for the small elastic motions of a variety of planar, flexible, multilink systems arranged in chain topologies, in which the links are connected by pin joints. Each link is represented as an Euler-Bernoulli bar in transverse vibration.

Application of perturbation techniques to flexible multibody system dynamics
Computers & Structures, 1987A matrix perturbation technique is developed for flexible bodies (substructures) that undergo large reference translational and rotational displacements. Although the governing dynamic equations of motion of such systems are highly nonlinear because of the large angular rotations and the resulting nonlinear inertia coupling between the reference motion
