Fatigue Testing
Creating Tests from ATV Field Data
Use recorded data to replicate the operation of a component. The result is a test profile that closely reflects—or is equivalent to—the field.
FATIGUE DAMAGE SPECTRUM
Use recorded data to create an accelerated random test that represents a lifetime of fatigue damage.
FIELD DATA REPLICATION
Reproduce recorded field acceleration measurements on a shaker. The software performs an iterative time-history playback to replicate waveforms.
SINE TRACKING, ANALYSIS AND GENERATION (STAG)
Generate an accurate representation of an environment with dominant sinusoidal vibration and background random vibration, such as an engine environment.
Evaluate Performance
Build and Run a Shaker Test Profile
An ATV’s tires and suspension system help to dampen vibrations, but new parts add weight, and the motor introduces random and rotational vibration. ATV product development requires testing to evaluate comfort compared to recommended values.
- Generate vibration tests from recorded or historical data, including random, sine-on-random, and shock
- Run profiles from test standards, such as MIL-STD-810
- Measure amplitude at contact points such as the seat and handlebars in the x, y, and z directions
- Output customized reports manually or on a schedule
- Examine the coupled effect of the power drive and trail conditions with a transmissibility plot
Order Tracking and Analysis
Examine Rotational Behavior
Analyze the response of the motor system to different RPMs and identify how the component’s vibration contributes to the overall level. Order analysis helps locate and prevent product failure relating to rotational sources of vibration.
- Analyze the noise and vibration of a motor or other rotational component
- Run a ramp up or coast down to evaluate the effects of change in speed
- Separate rotational content from the background random
- View the strength of a signal over time/angular velocity at various frequencies
- Compare data in different domains
Identify Resonances
Resonance increases the intensity of the natural vibration and leads to damage or failure.
Sine Testing
Automatically detect resonances using a swept and/or fixed-frequency sine wave test with control of acceleration, velocity, and displacement. Then, use a sine resonance tracked dwell (SRTD) test to determine the number of cycles required to generate a failure at a specific resonant frequency.
Modal Testing
Modal software divides a complex response into simple mode shapes, each with individual parameters that describe the item’s response to excitation. The overall response helps engineers determine resonances and validate the design.
