ENGINEERING TOOLS AND METHODS
SESSION TWO • Modal Analysis • Convergence of Frequencies • Rigid Body Modes • Properties of Lower and Higher Modes
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 (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. 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 (I.D.# WB1241).
