Vibration Analysis Using Finite Element Analysis (FEA) Web Seminar RePlay
This RePlay introduces vibration analysis performed with Finite Element Analysis (FEA). By considering time-dependent loads and inertial and damping 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, and frequency response will be covered.

Participants should have a degree in mechanical engineering and have some experience with FEA either by participating in the SAE Finite Element Analysis for Design Engineers on demand course or Seminar or through equivalent work experience. Familiarity with Windows OS and some CAD is helpful. The textbook, ?Engineering Analysis with SolidWorks? Simulation? by Paul Kurowski, is recommended reading.
Course information
Finite Element Analysis (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 everyday 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 course will enable participants to expand the scope of FEA to vibration analysis to simulate product behavior under those conditions.
All topics are illustrated using FEA software, SolidWorks? Simulation, for which participants will be provided a student license (compatible with 64-bit Windows 7 SP1, 8.1, 10; IE 10,11; MS Excel and Word 2010, 2013, 2016) and opportunity to practice skills learned. Acquired skills, however, will not be software specific and no prior exposure to FEA software is required.
