ARTeMIS Modal 6.0 Released

ARTeMIS Modal 6.0 has now been released and includes many new features and enhancements. Existing users should log in at www.svibs.com and download the latest build 6.0.0.2. If you are not already a user and wish to try it out, please go to the Download section to get a 30 days trial version.

New features and layout

ARTeMIS Modal 6.0 has many new exciting features. Some of these are

1. Mode shape uncertainty estimation (SSI-UPCX only).
2. Modal Alignment window for all estimators driven by a stabilization diagram.
3. Automatic Mode Estimation in Frequency Domain Decomposition methods has been improved, and can now also be operated using a graphical slider for the MAC Rejection level.
4. Data Acquisition plugins combined with EMA plugin enable impact testing directly in ARTeMIS Modal.
5. Software platform now supports both Tabbed and SDI layouts.
6. Multiple animations can now be exported automatically in AVI and GIF formats.

Please have a look at this YouTube video that introduces some of these new features:

Mode Shape Uncertainty Estimation in SSI-UPCX

From the release of version 6.0, mode shape uncertainties can now be estimated in the SSI-UPCX modal estimator. All modal parameters and their uncertainties can, as such now be estimated, presented and exported to third party software.

Figure 2: Uncertainties of global modes estimated using SSI-UPCX estimator. Natural frequencies and damping ratios and their confidence bounds can be visualized in the Frequency vs. Damping diagram. Mode shape uncertainties are presented in the Complexity diagram where the real/imaginary confidence bound is presented for each DOF. Mode shape animations also includes an option to visualize the uncertainties. In the mode list all modal parameters, including the mode shape complexity, are accompanied by the estimated standard deviations.

Modal Alignments

In all the estimators that uses a stabilization diagram, it is now possible to view the modal alignments for the individual global modes. The modal alignments display the natural frequency, damping ratio and mode shape complexity respectively as a function of the state space model dimension.

Figure 3: The top view depicts the modal alignments for the global mode selected below. The natural frequency, damping ratio and mode shape complexity development over increasing model dimensions are displayed along with estimated standard deviations (SSI-UPCX only).

Special ARTeMIS Bundle Offers – Valid until 31 March, 2019

If you are interested in Experimental Modal Analysis (EMA), with or without Direct Hardware Control, we are running a special limited offer, on all versions of ARTeMIS Modal.

Buying a license of any version of ARTeMIS Modal bundled with the EMA plugin and optionally a Direct Hardware Control plugin, can be done at a very affordable bundle price.

Please contact sales@svibs.com for more information or a quotation.

See you at IMAC-XXXVII and IOMAC-2019

We will be demonstrating all the new exciting features of ARTeMIS Modal 6.0 at the International Modal Analysis Conference (IMAC) in Orlando, Florida on January 28-31, in booth #213. We are also present at the International Operational Modal Analysis Conference (IOMAC) in Copenhagen, Denmark on May 13-15, 2019.

Next User Training Course

The next user training course will take place in Aalborg, Denmark on October 29-30, 2019.

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 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 instructor is Dr. Palle Andersen, CEO at Structural Vibration Solutions A/S.
