Formulation of flexible multibody systems using residual stiffness.

Gradient-Based Optimization of Flexible Multibody Systems Using the Absolute Nodal Coordinate Formulation

Lightweight techniques are applied increaslingly often for modern machine designs, such as industrial robots or machine tools, to reduce the moving masses and therewith the energy consumption. However, as a result the stiffness decreases and considerable deformations arise. Thus, for a proper system analysis the method of flexible multibody systems has to be employed. For the optimization of su...

Simulation of Flexible Multibody Systems Using Linear Graph Theory

This chapter provides a general description of a variational graph-theoretic formulation for simulation of flexible multibody systems (FMS) which includes a brief review of linear graph principles required to formulate this algorithm. The system is represented by a linear graph, in which nodes represent reference frames on flexible bodies, and edges represent components that connect these frame...

Method of Transformation from Inertial to Reference Frame Formulation of Flexible Multibody Systems

This paper presents a method of the reformulation of equations in the inertial frame formulation to the floating frame formulation. Results of a simulation example, performed using the modal transformation, show the good agreement with the standard inertial frame methods.

Modeling Intermittent Contact for Flexible Multibody Systems

This paper consists of two parts. The first part presents a complementarity based recursive scheme to model intermittent contact for flexible multibody systems. A recursive divide and conquer framework is used to explicitly impose the bilateral constraints in the entire system. The presented approach is an extension of the hybrid scheme for rigid multibody systems to allow for small deformation...
