New LMS TecWare Rev 3.1 substantially accelerates load data analysis
New Rev 3.1 introduces new automated procedures to consolidate, analyze and share load data
A critical factor for successful mechanical engineering is gaining a precise understanding of the loads that products will undergo during their anticipated lifetime. The availability of realistic load data is vital for running reliable simulations and rig test campaigns. To better support test and simulation driven mechanical engineering, LMS releases LMS TecWare Rev 3.1, featuring a webbased load data management capability
that facilitates the use of realistic load data throughout the entire development process. New is also the powerful graphic environment that streamlines the complete load data processing chain – from raw load data to load histories for driving virtual and physical durability rig tests. LMS TecWare Rev 3.1 also excellently applies to optimizing existing test schedule definitions and creating new (customer-correlated) test
schedules.

Using the broad range of load data processing capabilities that are available in LMS TecWare Rev 3.1, engineers are able to efficiently analyze the vast
amounts of accumulated load data. Besides effective load data cleaning and validation, LMS TecWare focuses on monitoring and comparing essential loading aspects from a durability perspective. Reports consisting of any combination of time histories, rainflow matrices, frequency information, statistics and fatigue predictions are essential in selecting representative loading scenarios for further test and CAE based durability engineering. They also contribute to acquiring the necessary engineering insight to improve
the correlation between different sets of load data, regardless whether the data originate from test, simulation or design.

Brand new in the Batch module of LMS TecWare Rev 3.1 is the so-called ProcessBuilder, a dedicated graphic environment for defining, optimizing and executing specific sequences of LMS
TecWare load data processing tasks. No programming skills are required, since ProcessBuilder allows process schemes to be intuitively defined by dragging, dropping, copying and pasting individual process blocks. Each block defines a specific action that needs to be performed on the data, such as for
example time signal viewing and editing, filtering, spike/drift/offset removal, rainflow counting or Power Spectral Density (PSD) calculation. To keep a clear overview of a complex process that involves large volumes of load data,
Efficiently acquiring detailed durability-related insight
To automatically import load time data derived from test track measurements, rig test campaigns or virtual simulations, LMS TecWare offers an extensive set of data drivers, including but not limited to LMS Virtual.Lab, LMS Test.Lab,
LMS TecWare offers the means to group multiple connected blocks and display them as a single block. In addition, procedures set up in ProcessBuilder can be executed in parallel and around the clock, without any user-interaction, and can entirely be reused as part of a more complex process definition. ProcessBuilder also features powerful process debugging capabilities and parameter definitions that can be made dependent on processed channel data.

To automatically import load time data derived from test track measurements, rig test campaigns or virtual simulations, LMS TecWare offers an extensive set of data drivers, including but not limited to LMS Virtual.Lab, LMS Test.Lab,
IST RigSys, MTS RPCIII, NI DIADEM, nCode DAC, ASCII and Universal Binary. Since the interactive inspection and consolidation of each individual signal would take far too long, LMS TecWare provides the capacity to automatically locate any flaw in the acquired load data. To correct signal inaccuracies resulting from power failures, spikes, offsets or drifts, LMS TecWare offers multiple ways to implement data corrections manually
or automatically. Especially when dealing with a high number of channels, improved time editing features – such as easy scrolling and fast channel selection – further streamline the process of editing and handling time signals. Also the tabular channel display with convenient channel grouping capability illustrates LMS TecWare’s fit-for-purpose for dealing with large data sets. A core capability of LMS TecWare is its extensive range of dedicated durabilityspecific data interpretation methods – based on statistics, rainflow counting and
PSD calculation – that enable engineers to efficiently qualify and quantify the durability potential of load data. With this new release, LMS TecWare increases the availability of statistical representations, which now also include bar charts, spider diagrams and Weibull representations. In addition to statistical solutions, LMS TecWare provides the most complete offering of rainflow counting methods. It supports uniaxial rainflow counting (range pair and level crossing) as well as multiaxial rainflow counting, the latter maintaining inter-channel phase relationships through the use of linear channel combinations.

To efficiently publish and share load data processing results, LMS TecWare Rev 3.1 offers flexible reporting capabilities. Besides standard reports, LMS TecWare provides the possibility to configure the content and layout of reports according to personal preferences and company guidelines. LMS TecWare automatically generates reports in HTML and Microsoft Word format, and from Rev 3.1 on, it also
places report references in LMS TecWare data sets so that reports can be opened directly in Microsoft Word from within LMS TecWare. Sharing data sets between multiple users also becomes a lot easier because LMS TecWare is now capable of automatically updating all the links to the data. In addition, the new release of LMS
TecWare offers a convenient one-click printing option, which allows any LMS TecWare report or result file to be printed on the spot.
To efficiently search, retrieve and access specific load data sets or durabilityrelated analysis results from a large pool of accumulated data, LMS TecWare 3.1 tightly integrates LMS Tec.Manager, a unique web-based data management solution. This solution allows any file or database to be opened in a web browser and exhibited in a variety of graphical displays, each in its own native format. In addition, LMS Tec.Manager’s advanced data search queries – which operate on the basis of meta information – are able to quickly find and return a link to even the smallest piece of data buried among hundreds of thousands of files.
More effective test schedule definition and optimization
Since test drives of hundreds of thousands of kilometers are no longer an option in today’s compressed development cycles, manufacturers are urged to replace lengthy vehicle tests by equivalent accelerated laboratory tests or virtual simulations. LMS TecWare supports this critical shift by efficiently determining sets of compressed load time histories that preserve the same damage potential as originally present – enabling both the generation of new test schedules as well as the optimization
