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
