ME'scope ODS and Modal Training Course
Our most popular hands-on ME'scope ODS and Modal Analysis course is back, February 12-14 2019. Join us at the Vibrant Headquarters for this 3-day hands-on training seminar in Centennial, Colorado just outside of Denver.

This course takes a fundamental approach is understanding the details of ODS (Operating Deflection Shape) and Modal Analysis.  Many training courses spend 2-3 days discussing differential equations, Fourier Transforms, matrix mathematics, etc., etc. This course is different. We concentrate on fundamental dynamics relationships, simple guidelines and emphasize the underlying concepts with numerous case histories and visual animations. We believe that to do their job well, the vibration analyst needs to understand the basics of dynamic motion.

The ME’scope training portion of the course is built around a detailed project workbook (The ME'scope Workbook).  Each workbook project is presented as a step-by-step series of instructions using ME'scope. The various exercises will acquaint a new or novice user with the many functions of ME'scope.  

Course Date: February 12-14 2019
Course Tuition: $1,695.00
Instructor: Dan Ambre, president of Full Spectrum Diagnostics, and Vibrant staff.

Introducing Visual Rapid Test™
Visual Rapid Test™
Vibrant has introduced a new ME’scope package called Visual Rapid Test™. This new package employs a new testing method called "Slinky tm testing".  Slinky tm testing only requires two vibration response sensors and as little as a 2-channel acquisition hardware system. Either sensor or both sensors can be moved between acquisitions, thus forming a chain of Transmissibility measurements called a TRN chain. The TRN chain preserves the magnitude & phase relationship between pairs of structural responses in the chain.
After a chain has been acquired, it can be seeded with either an Auto spectrum, Cross spectrum, Fourier spectrum, or FRF to yield a single-reference set of measurements. These measurements can then be used to extract ODS’s and mode shapes of the test article.
This new method is faster, easier, more flexible, and less costly to implement than conventional ODS or modal testing methods. Since only the structural responses are acquired, it can be used for ODS testing of operating machinery, or for modal testing using an impactor or multiple shakers.

Check out the App Note 50 below for more details on Rapid Test.

ME'scope Application Note 50
Rapid Test™ Using Two Uni-Axial Accelerometers 
Every month we review one of the ME'scope Application Notes. This month we take at the new ME'scope Visual Rapid Test™ .

In this Application Note, a unique measurement and post-processing capability in ME’scope will be used to calculate a single-reference set of FRFs from random response data acquired with two uni-axial accelerometers. The acceleration responses at 30 points on an aluminum plate are simulated by applying a pure random force input at one corner of the plate and using a set of experimental FRFs to represent the dynamics of the plate. The random responses will be calculated using MIMO Modeling & Simulation, which is part of the VES-3600 Advanced Signal Processing option in ME’scope. This App Note contains a downloadable project with Hotkeys to walk through the simulated Rapid Test ™.

Next month we will look at App Note 51: Rapid Test™ Using Two Tri-Axial Accelerometers

Upcoming Vibrant Conferences
Visit us at the International Modal Analysis Conference (IMAC) in Orlando, FL January 28-31st 2019. IMAC is a conference and exposition focusing on structural dynamics, and has evolved to encompass the latest technologies supporting structural dynamics. This broad focus on structural dynamics includes topics in simulation and modeling, nonlinear dynamics, sensors, signal processing and control spanning the full range of engineering disciplines. https://sem.org/imac
