Modal Analysis using Hammer or Shaker Excitation

In modal analysis, a model of the dynamic properties of a structure is created. The model is described by a set of modal parameters from which the structural behaviour can be predicted in different situations. Modal analysis is used in a wide variety of applications from securing structural integrity to improving comfort.

Modal analysis has traditionally been performed by exciting the structure with a measured force using either a hammer or one or more shakers, and measuring the responses using accelerometers. This is often referred to as Classical Modal Analysis to distinguish it from Operational Modal Analysis using non-measured ambient or self-generated excitation.

The webinar will:

Introduce the idea of modal analysis
Give an overview of frequently used excitation signals
Describe how to perform measurements using impact hammer or shaker excitation
Explain how to use mode indicator functions
Give an overview of modal parameter identification techniques
Describe how to validate the obtained modal parameters
