| | | | | | | Multibody Analysis Activities
The Structures Section performs detailed analyses involving flexible bodies with time-varying characteristics and control algorithms. The software programs used are DCAP (based on a ‘fast’, ‘effective’ and ‘symbolic’ formulation), SIMPACK and SAMCEF Mecano.
Several Multibody Dynamics Activities have been performed by the Structures Section in support of numerous projects:
Spacecrafts:
- modelling unconventional S/C dynamics, including orbital environment disturbances
- control laws, including sensors and actuation dynamics
- coupled system frequencies and time responses
- docking phase analysis
| | | Launch Vehicle during lift off phase |
Launch Vehicles:
- non-linear time dynamic simulations for flexible bodies with time varying characteristics
- atmospheric environment including external disturbance
- launch vehicle flight dynamics-control interaction (directly imported into Matlab)
- frequency domain analysis
- multiple nozzles dynamics capabilities
- local analyses (gust response, lift off, multi-payload separations)
- collision avoidance
- data recovery procedure
| | | Flywheel application |
Structural Dynamics & Control:
- modelling complex devices and mechanisms
- control design
- coupled system frequencies and time responses
- modelling laboratory demonstrator dynamics and control
