Basic approach to analyze Vibration in systems

Basic approach to analyze Vibration in systems

Basic approach to analyze Vibration in systems

Hi experts,

I am currently working for a Air Cooled Hrat Exchanger firm. We very often need to perform modal analysis for chceking natural frequency structures whether they are resonant with fan frequency.

Any references for basic understanding of vibration analysis would be greatly appreciated.

RE: Basic approach to analyze Vibration in systems

I'd divide it up into two bits, getting good data and analysing the data. Luckily Bruel and Kjaer have taught generations of engineers to do the first bit. The primers at https://www.bksv.com/en/Knowledge-center have a great deal in them. The textbooks are also good.

For the analysis a random web search on Introduction to experimental modal analysis threw up many free resources. http://www.sandv.com/downloads/0101avit.pdf is pretty typical in that it is stronger on the analysis than the data acquisition.

Your local university may host 3 day introductory sessions on Modal Analysis by any of the major instrumentation companies, if so that will get you up to speed far faster than any book.

Incidentally there is a load of tosh written about both subjects, if you are looking for practical results. Eyeglazing accounts of matrix manipulation are a hint that you are reading about some computational farrago rather than real people's work in the lab.

Bruel and Kjaer used to offer week long seminars. I'll bet they still do. I just received an email link from Vibration Research. They do webinars:

Fundamentals of VibrationVIEW Part 2 Webinar
Random Vibration Theory

Hi Sir or Madam,
Please join us for the next Vibration Research educational webinar! This month we will be discussing Random Vibration Theory and specifically concentrating on the Power Spectral Density Graph.
After a brief introduction to random vibration testing theory, we will talk at length about the PSD calculation and how it is used in random vibration testing.

The PSD is the method used to observe and understand random vibration, it gives engineers and technicians the ability to view the distribution of a signals strength over a band of frequencies and is used to measure the strength of a signal. How is this PSD generated, what is the calculation actually displaying, and what methods are available for generating a smooth PSD?

Join us on November 16, 2017 to find out more!
Choose between the 9am or the 2pm sessions. After registering, you will receive a confirmation email containing information about joining the webinar.

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
