Dynamics testing evaluates a product’s ability
to withstand stresses occurring during normal and adverse operating
conditions.
These tests can also include conditions found
during transport and product installation.
Dynamics testing is common in commercial,
industrial, aerospace and military applications.
At E-Labs, Inc. our dynamics testing capabilities include the following:
Acceleration Testing
Acceleration testing is used to detect structural
and mechanical strength limits in objects that experience constant
acceleration. E-Labs can perform centrifuge tests to meet
acceleration requirements of MIL-STD-810 method 513.5, MIL-STD-202
method 212A, MIL-STD-750 method 2006 and other specifications. Our
centrifuge has multiple slip rings and RF connectors to meet all
your needs. E-Labs has adjustable fixtures that allow the test item
to be tilted and rotated in order to match combined load vector test
requirements.
Acoustic Noise Testing
Acoustic noise occurs when sound pressure waves travel
through the air and are measured in psi or decibels. We have the
instrumentation to measure and analyze the sound waves produced to determine
compliance to your specification.
Acoustic Noise testing is performed to MIL-STD 740 and
other standards, E-Labs has performed many acoustic tests for the US Navy on
submarine components, let us handle your requirements.
Classic Shock Testing
Classic Shock Testing is accomplished using many of our
capabilities here at E-Labs. The typical shock testing event can be
performed on our Ling Electronics 335 or UD T-508 vibration testing systems.
For tests that required higher levels or longer
duration, E-Labs has additional mechanical shock testing machines. Using
these shock testing facilities we can achieve custom shock levels to meet
our customers' needs.
At our lab, the test item size is never an issue from
small to large we can accommodate most any size unit. We can simulate such
profiles as the road shock to the shock of a torpedo hitting a submarine or
the side of a ship.
Combined Environments Vibration Testing
We have the flexibility to turn any of our vibration
systems into combined environments, combining temperature/humidity chambers
with electro-dynamic vibration shakers. The chambers can perform rapid rates
of temperature change and the vibration facilities can produce up to 20,000
force-pounds, at frequencies up to 2000 Hz. The durability of the product
is tested for each individual stress and also for the combined interaction
of all stresses. This will allow for quick exposure of any design or
manufacturing weaknesses.
Impact Testing
The Impact Test is designed to ensure that containers and packages can withstand the abuse that occurs during shipping and handling. During shipping packages can be dropped, bumped, and bounced around in the back of a truck, or in a train car during coupling. Whether a simple drop test or a massive rail impact, at
E-Labs we can test your containers so you can be sure that your product arrives intact. We cover several MIL standards and ASTM standards for impact testing.
Lightweight Hammer Shock Testing
E-Labs has lightweight hammer shock testing facilities
that test the ability of shipboard installations to withstand shock
loadings. These shock testing facilities are totally capable of performing
MIL-S-901 test requirements.
During lightweight hammer shock testing, an article is
fixed to an anvil plate which is struck by a pendulum hammer at 1, 3, and 5
foot heights. The anvil plate is struck at three orientations top, back, and
side blows. Testing sequence will depend on the operating condition that is
to be represented.
Shock Testing Services
Our shock testing engineers will condition, plot and
help you analyze up to 128 channels of real time data - Shock Response
Spectrum (SRS), Fast Fourier Transform (FFT) or modal analysis.
They will review the cause and effect of shock pulses
and help in estimating damage potential based on the analytical data
results. They will also be able to offer solutions for those scenarios that
do not meet specifications.
Vibration Testing
Vibration testing can help validate your design to see
if it will survive its intended environment. It simulates a variety of
transportation scenarios, operating environments, and the effect of external
vibration within a storage environment. Our vibration testing facility is
comprised of multiple electrodynamic shakers capable of providing over
20,000 force pounds performing multiple types of vibration such as sine,
random, sine on random, random on random and vibration analysis. They are
capable of product vibration in a single as well as multiple axis
configuration in order to meet your type of testing.
Test applications include transportation load
simulations, fatigue due to vibration, reliability testing, squeak & rattle
testing, fragility, production stress screening, and package testing, launch
simulation, in flight and gunfire vibrations among others.
Sine vibration testing is useful in detecting the resonant and harmonic frequencies of your product while Random vibration is useful to mimic actual field conditions.
Test applications include transportation load simulations, fatigue due to vibration, reliability testing, squeak & rattle testing, fragility, production stress screening, and package testing, launch simulation, in flight and gunfire vibrations among others.
