Modal Testing and Frequency Screening

Modal testing is widely used to either verify the Finite Element Analysis (FEA) work carried out on a component or to establish any modes that may sit within rotating machinery fundamental frequency ranges.  

HGL can work with a large range of component sizes, subject to the correct clamping devices being available. Our laser vibrometry capability additionally gives us the ability to use non contact methods with small components where traditional methods would have too great an effect on the results.

Our developed software solutions enable us to capture the modal test results and provide Modal animations.

HGL has been selected as the supplier of a new turbine blade production test facility to carry out blade frequency screening by a major European Gas Turbine manufacturer, demonstrating that HGL can help whether your requirement is for testing a single part or supply the entire facility to allow you to test many thousands of components.
