Convenience, productivity and safety

Smart test routines and the intuitive user interface of LMS Test.Lab Vibration Control deliver optimal productivity throughout the testing cycle. Users directly launch pre-defined standard test campaigns from their desktop, without having to worry about specific parameter settings. The test procedures embed all the details on the actual test setup and can be complemented with digital images. All test results are automatically annotated with consistent header information and stored in a searchable database, together with full information on the test setup and the complete test logging.

The LMS Test.Lab system guides users in the definition of standard and more complex test profiles, which eliminates possible errors before starting the actual test. The system also supports the definition of schedules for complex endurance programs, including loops and the execution of external applications. For trend analysis, automatic measurements can easily be programmed and scattered during each level of the test. An embedded digital scope assists the operator in troubleshooting the measurement setup and quickly diagnosing possible problems. 

LMS Test.Lab includes a fully automated SelfCheck procedure, which verifies the control loop for integrity and safety before running the actual test. The Self Check procedure starts with measuring the background noise on all channels, after which it injects a low-level shaped random into the loop. It then automatically ramps up the amplitude in user-defined stages until a specified signal-to-noise ratio is met, or until the drive reaches a specified limit. Finally, LMS Test.Lab measures the system response using a compensated spectrum, and prevents the initiation of the test in case of error detection.    

The LMS SCADAS III controller hardware has been designed with safety as a primary objective. The entire measurement chain is continuously monitored during testing for open or short circuits. Overload checks are carried out on several places in the signal paths, including upfront, full bandwidth checks on the anti-alias filters. Dedicated hardware circuits guarantee smooth shutdown of the output signals, even in case of power failure, to protect the structure under test. During closed-loop control RMS and line-by-line abort checking, the system performs single or multipoint control, drive limitation, sigma clipping, continuous open channel and overload checks. Fast loop times ensure a safe and reliable control loop with 100% test object protection.

The Test Sequencing Scheduler in LMS Test.Lab increases safety and productivity in case of product tests that require complex and extensive test profiles. Swept sine, random, shock and combined modes tests can be automatically sequenced, repeated and synchronized with external equipment. Alarms are permanently checked to properly interrupt the vibration control test and the external equipment when required. The measured data and run logging are automatically saved in the Test.Lab project database. E-mail or SMS messages can automatically be sent to keep the operator up to date on the progress of the test.

In addition to the online processing capabilities, LMS Test.Lab Vibration Control offers analysis tools for the most demanding testing campaigns. With the help of intuitive data navigation, user attribute-based search, comprehensive analysis functions and powerful displays, users can quickly visualize and interpret data, and analyze test results. 

LMS Test.Lab automatically generates reports with a single mouse click, which eliminates the extensive effort to document the entire test campaign. Full compatibility with Microsoft Office and embedded support of OLE/ActiveX technologies turns static reports into dynamic information files. Readers can dynamically adapt axis scaling, add cursors and change legends to create their own customized view on the test results.

LMS Test.Lab Vibration Control enables testing teams to move beyond the simple Ïpassed or failedÓ test result, and to effectively visualize, analyze, report, and share their work with others.
