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.

This six-session web seminar 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.

All topics are illustrated using FEA software, SolidWorks® Simulation, for which participants will be provided a student license and opportunity to practice skills learned. Acquired skills, however, will not be software specific and no prior exposure to FEA software is required. The eBook, "Vibration Analysis with SolidWorks® Simulation" by Paul Kurowski, will also be included in the course materials. In-class, hands-on exercises and between-session assignments will provide an opportunity to put what is learned into practice.

Learning Objectives
By participating in this web seminar, you will be able to:

  • Evaluate the importance of dynamic effects in product simulation
  • Analyze inertial and damping effects in structural response
  • Perform modal analysis, time response analysis and frequency response analysis
  • Apply proper FEA modeling techniques to model system vibration
  • Use vibration analysis as a design tool

Who Should Attend
The course will be of interest to design, R&D, project, and product engineers who already use 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 Finite Element Analysis for Design Engineers Web Seminar 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.

Registration Information
Registration for this live web seminar is available on a per-person basis, similar to purchasing a seat in a classroom. Participants attend an online session from work or home; anywhere with a PC with internet access (at least 56K) and a telephone. The fee includes one connection to the conference calls (toll free telephone number provided for U.S. and select countries*) and assigned personal ID number; one connection to SAE's online training center (via WebEx); and access to a secure course in the SAE Learning Center that contains the presentations, class session recordings, supplemental materials, and assignments.

Registrations will be accepted until 5:00 p.m. the day before the start of the web seminar, but early registration is encouraged to allow for pre-course set-up and instructions.

*Global toll-free telephone numbers are provided for many countries outside the U.S., but are limited to those on the WebEx call-in toll-free number list. Check here to see if your country has a global call-in toll free telephone number for this web seminar. If your country is not listed, you may still connect using the US/Canada Call-in toll number or Voice over Internet Protocol (VoIP).

Although WebEx Training Manager will automatically launch when you join the web seminar, you or your system administrator are encouraged to download the plug-in in advance to help ensure successful setup. Click here, then follow the onscreen instructions.

NOTE: The course presentation will be recorded and made available for 30 days to those who register by the deadline.
