Approaches and possible improvements in the area of multibody dynamics modeling [PDF]

A wide ranging look is taken at issues involved in the dynamic modeling of complex, multibodied orbiting space systems. Capabilities and limitations of two major codes (DISCOS, TREETOPS) are assessed and possible extensions to the CONTOPS software are ...

Damping characterization in large structures [PDF]

This research project has as its main goal the development of methods for selecting the damping characteristics of components of a large structure or multibody system, in such a way as to produce some desired system damping characteristics. The main need

A full body musculoskeletal model based on flexible multibody simulation approach utilised in bone strain analysis during human locomotion

, 2011
Load-induced strains applied to bone can stimulate its development and adaptation. In order to quantify the incident strains within the skeleton, in vivo implementation of strain gauges on the surfaces of bone is typically used.

Multibody dynamics: Modeling component flexibility with fixed, free, loaded, constraint, and residual modes [PDF]

The assumed-modes method in multibody dynamics allows the elastic deformation of each component in the system to be approximated by a sum of products of spatial and temporal functions commonly known as modes and modal coordinates respectively. The choice

Recursive multibody dynamics and discrete-time optimal control [PDF]

A recursive algorithm is developed for the solution of the simulation dynamics problem for a chain of rigid bodies. Arbitrary joint constraints are permitted, that is, joints may allow translational and/or rotational degrees of freedom.
