NASTRAN interfacing modules within the Integrated Analysis Capability (IAC) Program [PDF]

open access: yes
The IAC program provides the framework required for the development of an extensive multidisciplinary analysis capability. Several NASTRAN related capabilities were developed which can all be expanded in a routine manner to meet in-house unique needs ...

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 decoupled recursive approach for constrained flexible multibody system dynamics [PDF]

open access: yes
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 ...

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

open access: yes
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.

Component model reduction via the projection and assembly method [PDF]

open access: yes
The problem of acquiring a simple but sufficiently accurate model of a dynamic system is made more difficult when the dynamic system of interest is a multibody system comprised of several components.

High speed simulation of flexible multibody dynamics [PDF]

open access: yes
A multiflexible body dynamics code intended for fast turnaround control design trades is described. Nonlinear rigid body dynamics and linearized flexible dynamics combine to provide efficient solution of the equations of motion.

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.

Zero-emission traction for rail

open access: yesRailway Engineering Science
Replacing the energy density and convenience of diesel fuel for all forms of fossil fuel-powered trains presents significant challenges. Unlike the traditional evolutions of rail which has largely self-optimised to different fuels and cost structures ...
