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.

A Reasoned Attempt to Mitigate Vibrations in Nonlinear Flexible Systems Influenced by Tractive–Elastic Rolling Contact Friction Through Input Shaping: A Case Study on a Trolley–Pipe Benchmark Transport System

open access: yesActuators
The well-regarded feedforward control strategy known as Input Shaping is aimed at improving the dynamic response of flexible mechanical systems by reducing overshoot and residual vibration amplitude.

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.

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

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 ...

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 ...

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.
