Simulating Shock & Vibrations in the Laboratory

Testing Labs
Performing shock and vibration testing in a simulated environment can be very
expensive and require complex equipment and setups. But there are test laboratories
that can offset some of these costs (although their services will still be several thousand
dollars). Midé has had experience with both National Technical Systems (NTS), and
Dayton Brown. For larger systems, like those being qualified for naval ships, Hi-TEST
laboratories offers shock and vibration testing services. This includes their MIL-S-901D
shock testing capabilities that consist of exploding a charge underwater to subject a test
setup to a large displacement shock event. Midé has been down there a couple times
for our bulkhead shaft seal and stern tube seal product lines as well as for some of our
general R&D programs. It is both exciting and nerve racking to witness those tests!
