Classes

ASD provides our clients with on-site training classes. We have put together four unique short courses to improve your team’s capabilities. Below are the four courses with brief description of each.

• Finite Element Modeling for Engineers:

  A short course to help engineers clearly understand the assumptions and underlying theory of the finite element method, finite elements and their assumed shape functions. Emphasis on practical modeling practices, rather than mathematics.
  • Practical modeling
  • Modeling structural interfaces
  • Effect of mesh size
  • Model reduction to dynamic math model
  • Necessary reduced math model mathematical checks
  • DAMVIBs study results/conclusions
  • Finite element/test correlation

• Structural Dynamics I:

  A short course covering linear structural dynamics theory and application.
  • Response of structures to various forms of transient forces
  • Response spectra and application to response calculations
  • Multi-DoF systems and the modal expansion
  • A survey of component dynamic reduction methods and applications
    • Residual vectors
    • Residual flexibility
  • Component-mode synthesis
  • Mode acceleration/mode displacement recovery methods
  • Damping
  • Application to launch vehicle/payloads linear transient coupled loads analysis

• Structural Dynamics II:

  A short course covering the response of linear structures to random excitation.
  • Underlying theory of random vibrations
  • Sound generation due to turbulent boundary layer mixing
  • Random vibration mass attenuation
  • Application to launch vehicle/payloads systems:
    • Liftoff acoustics
    • Transonic turbulent boundary layer
    • Calculation of mass attenuated structural-borne random vibration environments
  • Brief discussion on alternative methods for random vibration analysis and applicability
  • Statistical Energy Analysis (SEA)

• Structural Dynamics III:

  A short course covering response of nonlinear structures to dynamic excitations.
  • Underlying theory and fundamentals
  • Impact of friction, deadbands, nonlinear springs, nonlinear dampers, straps, snubbers, bumpers, contact/separation...
  • Application to launch vehicle/payloads CLA (nonlinear CLA)
  • Nonlinear CLA involving component interface deadbands
