Today I’d like to mention a couple things of administrative nature.

First of all – thanks to all of you who use this site! In the first three weeks the ABRAVIBE toolbox alone has been downloaded almost 500 times! We are very grateful for your support!

We have noticed that some users register but never activate their account. This could be because the registration email end up in your spam folder. We do mention this in the text during the registration process, but if you have missed it – take a look for the registration email in your spam folder.

Another thing is feedback. If you have trouble registering, or downloading, we really want to hear about it! Use our contact form here, to notify of what is going wrong.

You can also use the social media to share your thoughts about us! Or why not suggest an idea for what you would like to see as a vibration example.

Welcome to the new site – the official home page for the ABRAVIBE toolbox!

The Learn More! part of the site is designed as a blog, which gives some advantages; among other things you can subscribe to RSS feeds so you are notified every time a new resource is published here.

The site is intended to be a portal for learning, teaching and utilizing vibration analysis. You will be able to browse through examples of how to use the ABRAVIBE toolbox. You will also find resources that teach general vibration engineering, and resources for the book “Noise and Vibration Analysis: Signal Analysis and Experimental Procedures,” by Anders Brandt, published by John Wiley and Sons 2011.

If you are a previous user of the ABRAVIBE toolbox, you can now download the latest version by signing in to this site (after signing up for a user account). You will then be able to browse all the resources on this site, and optionally you can select to be notified by email next time there is an updated toolbox version available.
