The Data and What it Looks Like:
Importing Data into Random:
Fatigue Comparison Technique:
Measure your products fatigue and calculate its lifespan.
For years people have used methods to calculate the lifespan of a product based on the material s/n curve. With FDS, rain flow analysis techniques from your product are applied to the actual measured vibration, equivalent fatigue is quantified and time to failure is calculated. Commonly used life acceleration techniques are applied to shorten test time.
Custom Frequency Axis
Normally, random import is calculated linearly based on number of lines. The FDS is calculated on a custom logarithmic frequency axis. You can set the frequency axis spacing and the start/end frequency on the user interface. User is in control of how many points and which points to calculate.
Time Domain Calculation
Calculation through time domain, not frequency domain to account for kurtosis you will likely see in the real world. The Fatigue Damage Spectrum is based on the response of single degree of freedom systems rather than FFTs.
Display Imported File Statistics
Displays peak acceleration, velocity, displacement as well as the kurtosis of the time history file. This provides a quick and easy way to determine the statistics of a waveform.
Configurable Process Parameters
The user can define the slope of the s/n curve (beta) and quality factor (Q).
Reduce Test Time
User sets test item target life based on product specifications, as well as test duration. The software automatically calculates ratios that will produce the same amount of fatigue damage in shorter test time.
Analysis to Control
With one mouse click, bring your new random breakpoints into a control profile. Go from a time waveform to a breakpoint profile and start controlling on that profile all in one program.
Multiple Waveforms
Calculate the combined fatigue of multiple waveforms. Overlay and compare multiple waveforms on a single plot.
Includes Random Import (VR9204)
