Multibody dynamics model building using graphical interfaces [PDF]

open access: yes
In recent years, the extremely laborious task of manually deriving equations of motion for the simulation of multibody spacecraft dynamics has largely been eliminated.

Energy-Entropy-Momentum integration of discrete thermo-visco-elastic dynamics. [PDF]

open access: yes, 2011
A novel time integration scheme is presented for the numerical solution of the dynamics of discrete systems consisting of point masses and thermo-visco-elastic springs.

A simulation of the instrument pointing system for the Astro-1 mission [PDF]

open access: yes
NASA has recently completed a shuttle-borne stellar ultraviolet astronomy mission known as Astro-1. A three axis instrument pointing system (IPS) was employed to accurately point the science instruments.

Modeling of control forces for kinematical constraints in the dynamics of multibody systems: A new approach [PDF]

open access: yes
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.

Determination of Energy Losses of the Crank Press Mechanism

open access: yesMachines
This paper focuses on determining the friction energy loss in the mechanism of a mechanical crank press. After defining the crank press mechanism and how it works, we describe the energy balance of a technological operation—forming.

Space station attitude disturbance arising from internal motions [PDF]

open access: yes
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.

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

open access: yes
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

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

open access: yes
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 ...
