PREAMBLE

Dynamic Finite Element analysis (FEA) is used at for design verification and design optimisation. Dynamic analysis ranging from routine mode shape and mode displacement calculations, impact and crash analysis, transient dynamics, vibration induced fatigue etc, are carried out routinely by FEA analysts. This designer has to ensure that the intended functional requirements are met. Towards this, designers will have to rely on the results of FEA by analysts. This leads to many questions which the analysts have to answer:

  • How can we create robust FEA model?
  • How best can we capture the physical reality in our FE model?
  • How do we validate our FE models using analytical, closed form solutions?
  • How to check and control the quality of our Finite element models?
  • How do we impose confidence and defend our dynamic FEA report?
  • …. And many more

OBJECTIVE OF WORKSHOP

Workshop is aimed to give practising FEA engineers

  • theoretical inputs
  • tips for best practices in doing dynamic finite element analysis
  • identify common mistakes and methods to avoid the same
  • methods to validate the dynamic FEA results using analytical methods
  • to provide a platform for interaction between users, experts.

TOPICS COVERED

  • Basics of Vibration, single and multi DoF systems, resonance, vibration isolation and damping
  • Hand Calculation of vibration problems and comparison with FEA
  • Basics of FEA dos and don’ts, quality control of FE models
  • Modal analysis, mode shapes, harmonic analysis
  • Transient dynamic analysis, time history problems sine, shock, bump, blast analysis
  • Impact, crash and drop analysis
  • PSD and FFT
  • Comparison of FEA with vibration measurements
  • Vibration induced fatigue
  • Conceptual FEA model building and development

WORKSHOP Methodology & benefits of participation

Highly interactive workshop will have a combination of the following.

  • Lectures by experts with decades of experience

    • Creating a whatsapp group and email group for technical interactions

Who can participate?

All engineers and analysts who are engaged / interested in finite element analysis can participate.

WORKSHOP will NOT be based on any specific software platform. Users of all commercial or open source FEA software tools can participate.

Workshop will NOT be aimed at any specific vertical. Engineers from all verticals including automotive, aerospace, railways, defence, nuclear energy, thermal power, wind, medical equipment, electrical and electronics etc, can participate

NOTE:

  • Workshop will be intensive and is expected to be of 10-12 hours (or more!!) each day.
  • Workshop will not be based on any particular FEA software.
  • Participants are encouraged to bring their laptops with FE software of their choice to solve simple FE problems
  • Emphasis will be on understanding the physical problem and creating a conceptual model and elimination of defects and errors in finite element model creation.

ABOUT ProSIM.

ProSIM is a collaborative R&D and engineering services company with focus on simulation technology.
