Dynamics Testing
|
|
Dynamics testing evaluates a product’s
ability to withstand stresses occurring
during normal and adverse operating
conditions. These can also include
conditions found during transport and
product installation. Dynamics testing
is common in commercial, industrial, and
military applications. At E-Labs, Inc.
our dynamics testing capabilities
include the following: |
|
|
|
|
|
|
These tests can be performed
individually or in combination with
temperature cycling and hydraulic flow
tests. |
|
|
|
|
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. |
|
|
Classical Shock Testing
Classical Shock Testing is accomplished using many facilities 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 customs 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 3 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, with 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. |

|
Lightweight Hammer Shock Testing
E-Labs has light weight 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 3
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,
among others. |
