Vibration Testing and Shock Testing Services

Technology

From sub-atomic particles all the way around skyscrapers, internal movements and motions resulting from the absorption of energy make all objects vibrate to some degree. This fact ensures that in a global full of energy and movement, vibrations — or the oscillating responses of objects when moved from a situation of rest — will be the norm.

Some vibrations are expected and even needed for products to work as expected. As a great example, consider traditional speakers that turn energy into vibrations, which ultimately allows music lovers to listen to a common singers and musicians. Another example may be the tightly stretched diaphragm contained in the chest bit of a stethoscope, which, when excited by sound waves, allows a physician to listen to a patient’s heartbeat and/or breathing.

Of course, not totally all objects vibrate in a way that’s helpful as well as intended. For example, there probably isn’t a civil engineer alive who doesn’t know the story of the Tacoma Narrows Bridge and how 40-mile-per-hour winds induced its collapse because of structural labs for testing product vibration. As for the rest of us, we realize of the bridge’s final, fateful moments on November 7, 1940 thanks to the frequently viewed footage captured by camera store owner Barney Elliott. The film shows the bridge entering violent wavelike motion before breaking up and falling into Washington State’s Puget Sound below.

A more recent example of unintended vibration may be the now famous June 10, 2000 opening day of London’s Millennium Footbridge. The combined synchronous movements of pedestrians caused what’s known as positive feedback — a swaying motion emanating from the natural human instinct to stay balanced while walking. The result triggered Londoners dubbing the structure the “Wobbly Bridge.”

Fortunately for manufacturers and consumers alike, the materials and products we count on today in sets from airplane wings to suspension bridges are created stronger and more reliable thanks in large part to vibration testing labs.
