As specialists in dynamic testing, we provide equipment capable of exerting a 6,000 to 40,000 pound force with the capacity to perform closed-loop control from a single input to multiple channel inputs (from 2 to 32) with averaging or notched channel control. Vibration control systems can be programmed for real time monitoring, scheduled for length of time, or level scaled by dB or percentage, or scaled at various durations at different acceleration levels.
We have electro-dynamic shakers at 2-inch stroke and servo-dynamic shakers at 4-inch stroke with a range of capabilities. Most of our electro-dynamic shakers are attached with slip-plates to perform multi-axis testing. Environment Associates has both Unholtz-Dickie and Ling equipment with large size slip tables to fit most test articles and fixtures.
Environment Associates performs vibration tests to MIL-STD-810, RTCA DO-160, MIL-STD-750, MIL-STD-202, as well as ISTA, EN, IEC, and ASTM specifications. We also provide unique tests like gunfire, transportation packaging and NAVMAT screening.
Environment Associates can setup and provide the following vibration test profiles:
Sine – Can operate swept sine or fixed frequency sine wave vibration tests that can be controlled for acceleration, velocity or displacement
Sine on Sine –Operating a mixed-mode tests with multitude sine tones.
Random –Controlled spectrum random tests with spectrally shaped gaussian amplitudes
Sine on Random – Operating a mixed mode test with sine tones on a random background
Random on Random –Operating controlled spectrum random tests with swept random tones
Shock – Standard classical shock pulses
SRS – Shock Response Spectrum analysis.
Field Data Replication – Reproduce actual acceleration waveforms measured in the field.
