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 ...
MIL-STD-810 is maintained by a Tri-Service partnership that includes the United States Air Force, Army, and Navy. [2] The U.S. Army Test and Evaluation Command, or ATEC, serves as Lead Standardization Activity / Preparing Activity, and is chartered under the Defense Standardization Program (DSP) with maintaining the functional expertise and serving as the DoD-wide technical focal point for the ...
Topics covered at the symposium include shock-ship testing, water shock, weapons effects (air blast, ground shock, cratering, penetration), shock physics, earthquake engineering, structural dynamics, and shock and vibration instrumentation and experiment techniques. Over 200 technical papers were typically presented.
Testing at the physical environmental conditions (shock, vibration, temperature, altitude, humidity, etc.) that simulate those encountered over the operational life of the component. Random vibration and temperature cycling have proven to be the most successful forms of ESS in terms of effective flaw precipitation.
Pyroshock, also known as pyrotechnic shock, is the dynamic structural shock that occurs when an explosion or impact occurs on a structure. Davie and Bateman describe it as: "Pyroshock is the response of a structure to high frequency (thousands of hertz), high-magnitude stress waves that propagate throughout the structure as a result of an explosive event such as an explosive charge to separate ...
The medium weight test is a test performed on the medium weight shock machine. Weight of the test item including fixture to attach it to the test machine shall be less than a maximum of 7,400 pounds (3,400 kg). Heavyweight. The heavyweight test is a test performed on a standard or large floating shock platform.
Shock and vibration data from multiple replicate shipments can be used to: compare the shipment severity of different routings or of logistics providers; [5] or develop composite data to be used in package testing protocols. The shock handling data is often most useful converted from accelerations to drop heights or other means of quantifying ...
The norm describes the test procedure for airborne equipment. 8.0 Vibration: Aircraft type dependent test checks the effects of vibration and the equipment's ability to operate during all vibration scenarios. 9.0 Explosion proofness: These tests subject the test article to an environment under vacuum, with a gaseous mixture of combustibles.
