  • Vibration Analysis with FEA
    June 26, 2014 - June 27, 2014
    9:00 am - 4:30 pm

Cost: $375 +GST (Includes lunch both days)

For many years, a broad range of industries have used Finite Element Analysis (FEA) as a critical tool for product design and development. Recent performance advances in hardware have allowed a corresponding increase in sophistication of FEA software, enabling the development of more advanced FEA applications such as vibration analysis.

FEA is typically implemented in the design validation process. Analysis results are used as a basis for evaluating the integrity of the initial design and determining the effects of potential design modifications. Generally these applications have been confined to static analysis. Vibration analysis with FEA, which includes inertial and time-dependent loading effects, results in a greater understanding of component response, thus reducing product development time and cost.

This workshop will provide those involved in mechanical product design and development with a solid introduction to vibration analysis using FEA techniques.

By attending this two day workshop 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

Presented by Dr. Paul Kurowski, professor in the Department of Mechanical and Materials Engineering at the University of Western Ontario in London, Ontario.

Dr. Kurowski’s teaching experience includes FEA, machine design, mechanics of materials, mechanical vibrations, kinematics and dynamics of machines, and product development on undergraduate and graduate levels. He is also the President of Design Generator Inc, a consulting firm specializing in product development, design analysis, and training in Computer Aided Engineering methods.

Dr. Kurowski has published multiple technical papers and taught professional development seminars for SAE International, the American Society of Mechanical Engineers, the Association of Professional Engineers of Ontario, Parametric Technology Corp (PTC), Rand Worldwide, SolidWorks Corp., and other companies and professional organizations. He contributes regularly to several engineering publications focusing on the implementation of CAE methods in the product development process. He is a member of SAE International and the Association of Professional Engineers of Ontario. Dr. Kurowski obtained his M.Sc. and Ph.D. in Applied Mechanics from Warsaw Technical University and completed postdoctoral work at Kyoto University.

Who Should Attend

This workshop will be of interest to any mechanical engineer and designer 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 designers and mechanical engineers.

Opportunities will be provided to exchange and discuss analysis experiences and review problems of particular interest to participants. Although illustrative examples based on a specific software application package (SolidWorks Simulation) will be used throughout the two days, the workshop content is completely code independent.

Prerequisites

Attendees should have a background in mechanical engineering and some experience with FEA.
