Structural Dynamics

Wide Range of Capabilities


Quartus has a wide range of capabilities for performing structural dynamic analysis. Capabilities include:

  • Normal modes analysis including modal effective mass
  • Transient analysis for time-domain events
  • Sine vibration analysis
  • Random vibration analysis
  • Shock response spectra (SRS) analysis
  • Explicit analysis methods (Abaqus and LS-DYNA) for highly nonlinear elastic problems
  • Mechanism simulation including integrated stress/deflection analysis
  • Jitter and optical performance

Advanced Features


Quartus has extensive experience in advanced techniques including:

  • Superelements (substructuring) for large models, component mass and stiffness matrices, and efficient reanalysis
  • Fixed-interface (Craig-Bampton) modal synthesis method
  • Free-interface (MacNeal-Rubin and Hruda-Benfield) modal synthesis methods
  • Mode acceleration and residual vector methods for accurate responses
  • Data recovery matrices including accurate element forces and stresses
  • NastranDMAP alters for special analysis and output

Challenging Environments


Quartus can analyze complex structures and environments such as:

  • Launch vibration and acoustics for spacecraft
  • Electronic components for shock and vibration
  • Missile systems for transient and quasi-static loads
  • Aircraft hardware for vibroacoustic environments
  • Avionics enclosures for random vibration and shock conditions
  • Vehicle impact on land and water including airbag attenuation
