The Mechanisms 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), Adams, SIMPACK and SAMCEF Mecano.
Several Mechanisms Dynamics Activities have been performed in support of numerous projects:
Mechanisms:
- design and analyse mechanisms systems
- assess parametric design solutions and to optimise the performances of structures and mechanisms
- predict the static, kinematics and dynamic behaviour of mechanical systems
- animate the motion of dynamic, solid models
- simulate control loops incorporating mechanical parts, e.g. mechanisms active structures
- perform conceptual design studies and correlate test and analysis data
- investigate the performance and possible malfunction of mechanical systems, including in-orbit
- modelling complex devices and mechanisms control design
- coupled system frequencies and time responses
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 analyses
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
