New Experimental Modal Analysis Plugin
We have now released a new plugin for Experimental Modal Analysis (EMA) that works with all versions of ARTMIS Modal (Basic, Standard, Pro). The plugin opens for frequency domain estimation of modal parameters from Frequency Response Functions (FRF's) using either Complex Mode Indicator Function (CMIF) - Peak Picking or Rational Fraction Polynomial in Z domain (RFP-Z).
The FRF's can either be imported through Universal File Format from third party solutions, see a worked example here, or by using the new Impact Testing module, see a worked example here.
The Impact Testing module is available if valid plugin licenses for a data acquisition system and Experimental Modal Analysis are present on the computer.
International Seminar on Modal Analysis Conference (ISMA 2018)
We will be presenting the new RFP-Z estimator and Impact Testing Module at ISMA conference on September 17-19, 2018 in Leuven, Belgium. See you in booth 14!
Next User Training Course
The next user training course will take place in Aalborg, Denmark on November 6-7, 2018.
This 2-day course is for the new as well as experienced users that would like to be updated on Operational Modal Analysis and Experimental Modal Analysis as well as the latest features of ARTeMIS Modal software.
The course will be held on November 6-7, 2018 at Comwell Hotel Hvide Hus in Aalborg, Denmark. Both days we start at 9.00 and end at 17.00. There will be lunch and coffee breaks during the day and free WiFi internet access. The course instructors are Dr. Palle Andersen, CEO at Structural Vibration Solutions A/S and Mr. Ilija Trenchevski, senior developer of ARTeMIS Modal at Structural Vibration Solutions A/S.
On day 1, you will get a comprehensive introduction to Experimental Modal Analysis (EMA) and Operational Modal Analysis (OMA) in general. During this introduction, the differences and similarities between EMA and OMA will be described. Also the procedures for acquiring high quality measurements will be discussed in details. We will help each other acquiring good measurements of different demo structures both for EMA and OMA applications. The introduction is followed by a presentation of the user-friendly Frequency Domain Decomposition (FDD) technique, and we will analyze the acquired measurements as hands-on exercises. Finally, the two other FDD related techniques of ARTeMIS (Enhanced Frequency Domain Decomposition and Curve-fit Frequency Domain Decomposition) are introduced, and we will continue with hands-on exercises using these techniques. The technical programme will end with the analysis of the acquired EMA data using the Complex Mode Indicator Function - Peak Picking method (CMIF).
We end day 1 at a restaurant in the old downtown of Aalborg.
On day 2, you will be introduced to the advanced OMA methods called Stochastic Subspace Identification (SSI) as well as the parametric EMA method called Rational Fraction Polynomial in Z-domain (RFP-Z) and the latest features available in ARTeMIS such as the Structural Health Monitoring plugins.
You will get course material as well as a 1-month free demo version of the ARTeMIS Modal Pro which we invite you to install on your own laptop for use during the hands-on exercises of the course.
Attending the course will cost 950 EUR per person. Students get 50% discount. Book before August 31, 2018 and SAVE 10%!
