LMS Test.Lab Desktop
Faster than ever from acquisition to reporting
With LMS Test.Lab Rev 11, reporting has never been easier. Users can create their own report template and replace data origin or data at will. LMS Test Lab Rev 11 offers the possibility to replace existing project pictures with the data of any other project with a comparable structure. Starting from a template report, a full report can be generated in a single click just by replacing the source data location in the template. Replacing can be done on the level of a picture a project, a section or a run. Isolated corrections of the template report allow modifying the source of single measurement functions in the report.
- Single and double integration
- Single and double differentiation
- A,B,C,D and Linear Weighting on frequency data for frequency-based calculation
- Smoothing options on time and frequency functions and section scaling methods: RMS, Peak and peak-to-peak
The color map display also offers an extra set of processing functions: Integration, differentiation and weighting.
In LMS Test.Lab Rev 11, the LMS Test.Lab Desktop benefits from automation extensions and supports a wider range of data formats, such as the additional default supported data formats RPC3 data read and data write.

Handle your time data the most efficient way
The LMS Test.Lab General Processing has been enhanced to serve the needs of all applications by ensuring better time data handling and compiling.In LMS Test.Lab Rev 11, the filter capabilities have been improved: users can view the frequency response of a filter, define their FIR or IIR filters or create FIR-filters based on measured or manually defined FRF-functions.
The new signal generation function allows generating a sinusoidal, sweeping sine, triangle, square or random signal with a specified amplitude, frequency or phase.

Enhanced hybrid modeling capabilities help improve simulation models
Hybrid modeling is a technique that accelerates the modeling process and improves the quality and reliability of simulation results, by using in an optimized way component test data complementing CAE models. Hybrid modeling is often used when the CAE model is too complex to design or simply not available, while a physical prototype is already available.
LMS hybrid modeling capabilities bring in unique features that make the availability of an existing FE model superfluous. It is not needed anymore to acquire data over the full frequency range: a limited frequency range data set suffices. On a test model, LMS Test.Lab Modal Analysis allows generating rigid body modes in the lower frequencies and residual modes in the higher frequencies. The rigid body modes can be synthesized using the LMS Test.Lab Rigid Body Calculator or a newly implemented feature in LMS Test.Lab Modal Analysis, which lets users synthesize these modes starting from inertia properties.
The upper residual terms, found during model estimation, can be used in modeling calculations once they have been converted into static compensation modes in LMS Test.Lab Modal Analysis. Methods have been implemented to make all modes consistent before collecting them in one mode set. The resulted mode set, containing rigid body modes, flexible modes and residual flexibility, is described as the full modal model. This model can be further used with LMS Test.Lab Modification Prediction for more precise modification simulation or with LMS Virtual.Lab to replace a simulation component model by a full experimental modal model for different methods of sub structuring such as multi-body simulation (MBS), component mode synthesis (CMS) and FRF based sub structuring (FBS)

Improved displays simplify result interpretation
In LMS Test.Lab Rev 11, LMS Test.Lab Ground Vibration Testing lets users easily generate a high amount of displays such as lissajous displays via MS Office Excel in Test.Lab MIMO Normal Mode Testing. These displays can be organized in order to look like the actual test object for quicker identification of problem areas. Other LMS Test.Lab Rev 11 graphical extensions bring value to the LMS Test.Lab Ground Vibration Testing solution and LMS Test.Lab Structures solution such as:
- The automatic mode shape expansion animates non-measured DOFs without defining slave DOFs
- Displays overlay let users animate 2 modes on the same geometry for better visual interpretation of the mode differences
LMS Test.Lab MIMO Normal Mode Testing now includes a manual force quadrature method for user controllable damping estimation incorporated with external ergonomic tuning device. On the hardware side, the LMS SCADAS Mobile supports advanced structural testing applications, including Ground Vibration Testing.
Designed to help tackle new engineering challenges
LMS Test.Lab Rev 11 adds a new tracking mode on signature focus to RPM. The logical triggering allows the user to define a complex triggering condition based on a combination of conditions on different channels. The function supports rotating machinery testing on multi-shaft engines.
The new hardware module RV4 better supports torsional vibration testing. The RV4 module adds 4 tacho channels per module. Analog tachos, digital tachos and incremental encoders are supported.
LMS Test.Lab Rev 11 introduces frequency-dependent calibration. Frequency-dependent calibration improves data quality by correcting measurements that are deformed along long cables or by other transducers (e.g. distortions telemetry system in turbine testing systems). The correction is done online on the time data.

Complete portfolio of experimental acoustic solutions
LMS Test.Lab Rev 11 complements the portfolio of acoustic solutions. Especially the following acoustic and vibro-acoustic testing methods have been extended with new tools.
Sound source localization:
- The irregular near-field acoustic holography (i-NAH) method allows low-frequency analysis of a data set acquired with the LMS Test.Lab High Definition Acoustic Camera. The camera is the most versatile sound source localization tool with 3-in-1 functionality for both near & far-field measurements using beamforming, holography and focalization techniques.
- Video synchronization has been added to the software. The feature helps processing transient events as it becomes easier to relate a sound source to an event.
Extended pass-by noise & sound intensity applications:
The pass-by noise application now includes the UNECE Regulation 117 for tire coasting noise.
The sound intensity application has been extended with measurements of 2-rooms sound transmission loss based on sound intensity.
Sound quality:
The workbook includes new visualization tools:
- All modulations of one time trace are available in a single view
- The Stationary Modulation Maps help visualize modulations of a stationary signal
- The workbook is also complemented with .hdf file interface and fully supports HMS digital heads.
Transfer path analysis:
Being the leader on the market, LMS completes its portfolio of TPA solutions with energetic calculation for Auto power operational data. Energetic TPA provides a new type of operational input and is especially suited for uncorrelated sources, with an emphasis on high frequency content, where phase information is difficult to measure or unreliable. The convenient TPA contribution display (or 4D display) benefits from display extensions. Amongst others, path ranking can now be done based on a selected range between a double cursor.

The LMS SCADAS Mobile hardware now supports environmental testing applications. The XSI-V control module has been added to the hardware. The module includes connectors to the emergency shutdown controller, indispensible to all environmental testing applications. The LMS SCADAS Mobile supports the following workbooks: Sine Control, Random Control, Shock Control and Single Axis Waveform Replication.
The mission synthesis workbook features a number of improvements. Users can modify FDS units and values. When processing time data, they can handle an unlimited number of samples and select segments at will. A PSD confidence interval is now also available.
