Introduction to Experimental Modal Analysis

Dynamics Testing & Analysis Workshop: Introduction to Experimental Modal Analysis

When you are investigating a dynamic system how do you:-

  • Validate a computer model?
  • Determine the damping?
  • Establish the boundary conditions?

These are difficult issues for dynamic simulations. However, they can often be quickly and easily resolved by using the experimental approach known as modal analysis. This workshop introduced engineers to the methods and techniques of modal analysis showing how they can be used in support of a simulation, and more widely, to eliminate uncertainty. The workshop enabled those involved with simulation, to gain an understanding of the opportunities available from modal testing.

In the morning there were talks from leading experts who described the reasons for testing, the experimental and theoretical background and gave demonstrations of testing methods.

Practical Session

In the afternoon the delegates were able to try out modal testing for themselves on the military equipment at the Defence Academy.
