Training Class Description
Dynamic Analysis using FEA  
Many problems facing designers and engineers are dynamic in nature. The response of a
structure cannot be simply assessed using static assumptions.

The nature of the problem may be to understand the resonant frequencies of your design,
so that key driving frequencies such as equipment rotational speed, acoustic or external
pressure frequencies, ground motion frequency content or vehicle passing frequency.
Your design may face external driving forces from adjacent components; cams, push
rods, pistons or from vehicle input sources such as a bumpy road, wave loading, air
pressure or inertial forces.

Whatever the nature of the challenge, the objective of this course is to break down the
dynamic problem into clearly defined steps, give an overview of the physics involved and
show how to successfully implement practical solutions using Finite Element Analysis.

The course is held in partnership with NAFEMS, the only vendor neutral, not-for-profit
organization with the aim of promoting the effective and reliable use of FEA. The course is
Each topic in the class is treated as a building block and is presented using an overview of
the physics and theory involved. The math is kept simple and the emphasis is on practical
examples from real life to illustrate the topic. The mapping to Finite Element analysis
techniques is shown with numerous workshops. The tutor will be running analysis
interactively and involving the students in the process.

Students are shown the various approximation methods and how to judge which are
acceptable and appropriate for solving a wide range of practical problems. Practical
considerations of loadings, boundary conditions, damping and   structural details are shown
by numerous examples.

Of equal importance is the assessment and interpretation of results. This starts with
ensuring the modal frequencies and mode shapes are feasible and accurate. Techniques
are shown to confirm this and to make sure the basic modal response of a design is fully
understood. Comparison against test or hand calculations is shown. A range of hints and
tips are shown for producing subsequent efficient and accurate response analyses.
Interaction is encouraged throughout the course, with the planning and design of complete
FEA projects. Options for mass and stiffness modeling, damping, loads and boundary
conditions and solution methods are discussed with the students.  The tutor then runs the
analyses using this input and the results are investigated. Using this approach, classic
errors are shown and corrected in a real world scenario.

The final session covers a wide range of application techniques available and shows typical
applications and best practices across industry. The objective is to show students how to
assess the nature of the dynamic environment and what tools can be used, together with the
scope of the various solutions.
This course is aimed at practicing engineers who wish to learn more about how to apply
finite element techniques to dynamic analysis in the most effective manner. Ideally a
student should have some experience of FEA analysis, but this is not essential. The
material that is presented is independent of any particular software package, making it
ideally suited to current and potential users of all commercial finite element software
systems. This course is a must for all engineers aiming to use FEA as a reliable predictive
tool for dynamic analysis.
