design and provide recommendations to allow your products
and equipment to survive random and sinusoidal vibration.
The shock (abuse) tolerance of your products can be improved
through increasing their ability to store energy. These
can often be accomplished inexpensively, and often accompany
reductions in part count and manufacturing costs.
High Impact Shock Testing
has recently completed a High Impact Shock machine capable
of performing tests per Mil Std-901.
This machine is capable of testing “light weight”
equipment up to 550 lb. It
consists of a welded structural steel frame with a 400 lb
hammer that swings through a 5 ft radius arc.
The hammer strikes the backside of a mounting plate
to which the test equipment is attached.
This is a very energetic test.
The shock impulse generated is very large.
Its purpose is to simulate battle damage aboard US
Navy ships and US Army installations and vehicles.
The shock machine,
known in our laboratory as Thor, is readily available for
service on very little notice. Using our data acquisition capability in house, we can
monitor acceleration levels, displacement,
electro-mechanical function, or any other aspect of
performance of a Client’s test item during the test.
Dynamark Engineering has a
vast hardware cache for piecing together precisely the
custom test equipment needed by a Client.
Our inventory includes motors, hydraulic drive
systems, transducers of all types, strain gage equipment,
oscilloscopes, signal generators, signal analyzers, strobe
equipment, structural steel, and electrical equipment.
These items can all be modified as required in house
by our machine shop, soldering facility, welding facility,
press forming capability, etc.
cases, we find that we already have the primary components
necessary for a given job already in house.
This saves dollar cost for the Client as well as the
time expended to become familiar with some new test gizmo.
So the time savings realized by coming to us really
folds back into additional cost savings in terms of getting
your product out sooner and less direct engineering labor on
the project budget to get to the answer.
We have in general already gone through the
(sometimes painful) learning curve for the test equipment
that is needed.
