MDS - Machine Deflection Shapes - Adash - #1

Text version of the page

The Software system MDS is already in its fourth generation of development. The first version of MDS was created in 1989 and from that time it has been continuously developed and updated. The first version ran under MS-DOS, the next version under Windows 3.1 and the present version was created for Windows 95 and Windows NT. Why is measurement of Machine deflection shapes so effective and why is it so popular in the vibration diagnostic field? There are two answers, which represent two different views. For diagnostic personnel, MDS represents the ability to evaluate vibration behaviour and as a consequence the whole operational condition. The measurement is not restricted to bearings and similar parts, instead measurement points are uniformly placed on the whole machine and its frame. Only in this way can you reveal the very tricky types of failure, for instance, resonance problems. For people in maintenance departments MDS is the most effective and the fastest tool for revealing any condition change and its cause. The second view on the MDS system is that it provides a simple display of the machine's condition. So simple, that people who are not from a maintenance or vibration background have little difficulty in understanding it. This provides supporting evidence for the maintenance engineer when justifying maintenance projects to management and decision makers. Today hardly any manager is willing to study tables or graphs and, as time for explanations that repair is necessary is limited before failure might occur, this evidence is vital. Results from measurement, which is displayed by MDS is therefore the perfect tool. The simple animated pictures of the machine and its behaviour represent an excellent way to demonstrate the need of repair or show the result of repair.

Machine motion seen on the PC screen is a faithful copy of the machine's operational behaviour. The measurements show the cause of problem - looseness of the frame.
