Vibration Analysis using FEA: A Hands-on Workshop
I.D. # C0830 Duration 2 Days

FEA has been used by engineers as a design tool in new product development since the early 1990's. Until recently, most FEA applications have been limited to static analysis due to the cost and complexity of advanced types of analyses. Progress in the commercial FEA software and in computing hardware has now made it practical to use advanced types as an every day design tool of design engineers. In addition, competitive pressures and quality requirements demand a more in-depth understanding of product behavior under real life loading conditions.

This seminar introduces one of the advanced types of FEA: vibration analysis. By considering time dependent loads and inertial effects, vibration analysis allows for a more in-depth product simulation thus reducing product development cost and time. The course reviews basic concepts of vibration analysis and illustrates how they are implemented in FEA to simulate product behavior. The most common types of vibration analysis such as modal, time response, frequency response and random vibrations are covered. Participants will have the opportunity to practice skills learned utilizing the commercial FEA software SolidWorks Simulation.

Learning Objectives
By attending this seminar, you will be able to:
  • Evaluate the importance of dynamic effects in product simulation
  • Analyze inertial and damping effects in structural response
  • Use vibration analysis as a design tool
  • Perform time response, frequency response and random vibration analyses
  • Apply proper FEA modeling techniques to model system dynamic
Who Should Attend
The seminar will be of interest to any design engineer who already uses Finite Element Analysis (FEA) as a design tool and would like to explore if and how vibration analysis with FEA may benefit the design process. It builds on participants' experience with static FEA and on knowledge of mechanical vibrations common to any mechanical engineer.
Prerequisites
Participants should have a degree in mechanical engineering and have some experience with FEA either by participating in the SAE seminar ID# 93006 - "Finite Element Analysis for Design Engineers" or through equivalent work experience.
