Vibration Control – Control Options


Sine Notching and Random Response Limiting LR.jpg

Sine Notching and Random Response Limiting

LMS Test.Lab Sine Notching and LMS Test.Lab Random Response Limiting enable users to effectively protect test items against over-testing. While the average control signal level will match its reference spectrum, the response at particular points of the tested object may be very different, due to the resonances of the device under test. The vibration level at any channel (control or measurement) is limited by an auxiliary reference profile for maximum protection of the test item.

Combined Modes

The LMS Test.Lab Sine on Random (SoR) module offers the possibility to define a background noise level combined with up to ten fixed and sweeping sine tones. LMS Test.Lab Random on Random (RoR) option offers the user the possibility to define a background noise level combined with an unlimited number of fixed and sweeping narrow-band signals. Both options in combination with LMS Test.Lab Random Control allow the definition of complex profiles, typically called Sine on Random on Random (SoRoR).

Shock Response Synthesis LR.jpg

Shock Response Synthesis

LMS Test.Lab Shock Response Synthesis synthesizes a time waveform that corresponds to a user defined shock response using a series of superimposed wavelets. The synthesis module is seamlessly integrated in the shock control workbook.

Mission Synthesis

LMS Test.Lab Mission Synthesis helps define test specifications for single axis random and swept sine vibration testing from measured load data. Resulting test specifications are equal in damage and are accelerated for faster run times. Test tailoring methods as described in industry standards such as GAM EG-13, MIL-STD 810F and NATO AECTP 200 are used for this purpose. Multiple acceleration loading environments (defined in either time or frequency domain) are analyzed for fatigue potential by calculating MRS (maximum response spectrum) and FDS (fatigue damage spectrum).

Single Axis Waveform Replication

LMS Test.Lab Single Axis Waveform Replication gets field data to the shaker in fewer steps and extends current testing techniques from classical sine, tracked sine, random and shock control to long-duration time waveform replication. The easy-to-use, native MS Windows software requires little training and helps operators automate very long duration tests with full security. The workflow-based user interface of LMS Test.Lab assists the user throughout the complete test.
