Motors weighing 250 pounds (110 kg) or less shall be tested on the lightweight shock testing machine. Motors weighing in excess of 250 pounds and up to 6,000 pounds (2,700 kg) shall be tested on a medium weight shock testing machine. Motors weighing over 6,000 pounds shall be tested on a floating shock test platform or barge test.
Classical shock testing consists of the following shock impulses: half sine, haversine, sawtooth wave, and trapezoid. Pyroshock and ballistic shock tests are specialized and are not considered classical shocks. Classical shocks can be performed on Electro Dynamic (ED) Shakers, Free Fall Drop Tower or Pneumatic Shock Machines. A classical shock ...
Shock detector on a package Shock detectors can be mounted in sports helmets to help monitor impacts. A shock detector, shock indicator, or impact monitor is a device which indicates whether a physical shock or impact has occurred. These usually have a binary output and are sometimes called shock overload devices. Shock detectors can be used on ...
At some point prior to the actual test, the teacher was given a sample electric shock from the electroshock generator in order to experience firsthand what the shock that the learner would supposedly receive during the experiment would feel like. The teacher and learner were then separated so that they could communicate, but not see each other.
A shock data logger can be evaluated: separately in a laboratory physical test, perhaps on an instrumented shock machine; or mounted to its intended item in a testing laboratory with controlled fixturing and controlled input shocks; or in the field with uncontrolled and more highly variable input shocks.
This was achieved through laboratory shock testing of equipment prior to its installation aboard vessels. With the advances in computer simulation and modeling capabilities, it is now possible to simulate a vessel's response to an underwater explosion and to identify potential problems or failures without extensive field testing. By using DDAM ...

Shock tubes (and related impulse facilities such as shock tunnels, expansion tubes, and expansion tunnels) can also be used to study aerodynamic flow under a wide range of temperatures and pressures that are difficult to obtain in other types of testing facilities. Shock tubes are also used to investigate compressible flow phenomena and gas ...
