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

Controlled multibody dynamics simulation for large space structures [PDF]
Multibody dynamics discipline, and dynamic simulation in control structure interaction (CSI) design are discussed. The use, capabilities, and architecture of the Large Angle Transient Dynamics (LATDYN) code as a simulation tool are explained.

Modeling of control forces for kinematical constraints in the dynamics of multibody systems: A new approach [PDF]
Conventionally kinematical constraints in multibody systems are treated similar to geometrical constraints and are modeled by constraint reaction forces which are perpendicular to constraint surfaces.

Space station attitude disturbance arising from internal motions [PDF]
A source of space station attitude disturbances is identified. The attitude disturbance is driven by internal space station motions and is a direct result of conservation of angular momentum.

A decoupled recursive approach for constrained flexible multibody system dynamics [PDF]
A variational-vector calculus approach is employed to derive a recursive formulation for dynamic analysis of flexible multibody systems. Kinematic relationships for adjacent flexible bodies are derived in a companion paper, using a state vector notation ...

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 ...
