The good news is you are in the right place. We have developed an amazing set of 3D animations and simulations that even make the Category IV topics relatively easy to understand. Topics that were once only suitable for PhDs and math geniuses are now accessible to practical vibration analysts – as it should be.

Here are the main topics covered on the VCAT-IV course:
