Sine Tracking, Analysis and Generation (STAG) generates Sine on Random tests reflective of environments with dominant rotational tones that are rendered as sine tones on a shaker table. STAG is a real-world evaluation for products that may experience these dominant sinusoidal components, such as engine components.

While it is important to characterize these environments through testing, both the rotational and the random components of the real-world environment must be properly generated and analyzed.
The more accurate option is a combination of sine and random testing. A Sine on Random test can replicate dominant tones and orders as well as produce more consistent results.
The STAG test development procedure allows the user to analyze the order content of a waveform. Using that information the orders can be extracted and sine tone profiles that are easily accelerated can be generated. These accelerated sine tone profiles are then combined with the Fatigue Damage Spectrum analysis of the remaining random content. The STAG tool combined with FDS allows for the analysis, acceleration, and generation of a real-life test.
“The processing time [for standard SoR test development] took up to 30+ hours to create a test profile. This method was computationally expensive and caused a long run time. Many times, there were input errors to the band tracking filters and the wrong order was extracted, or the same order was extracted twice requiring another processing run.
With the STAG tool, our team was able to develop sine tone profiles for the sinusoidal components and then export the random content to VibrationVIEW to employ FDS. The other commercially available package was expensive and time-consuming while STAG processed the data in a fraction of the time and with greater accuracy.”

Develop tests and analyze data with software tailored for rotational equipment.
Save time and reduce transposition errors by quickly importing the analyzed data from STAG to VibrationVIEW. Orders are extracted from the recording before the background time waveform is processed with FDS. This ensures that FDS accelerates random data, and not sinusoidal data.
STAG can export a data file with the order content removed. This data can be analyzed and accelerated using the fatigue damage spectrum (FDS) tool in VibrationVIEW, which provides a test profile that exactly matches the shape of the recorded data.
