Shock Tests

Ship Board Shock Test

Shipboard, MIL-DTL-901E Test

Equipment on navy surface ships and submarines experiences many different types of shock. Aircraft launch mechanisms, steam catapults, tail hook stop cables and missile launchers produce a variety of shocks such as many combat situations, such as direct hit by the enemy army.

Gemi Bordası Şok Testi

The shock test on board includes two types of devices:

  • Class A equipmentis crucial to the ship's safety and constant combat capability.
  • Class B equipmentare items that are not required for the combat capability or security of the ship, but may be dangerous to the personnel or the ship as a whole if exposed to shock.

In addition, MIL-DTL-901E standards for ship shock testing divides devices into systems and subsystems, such as diesel generators, against the electric motor of the diesel generator. Test requirements for devices of each class are determined by how they are mounted on the ship:

  • Class I equipmentmust meet certain shock test requirements when installed, without the use of flexible mounting hardware between the device and the structure of the ship.
  • Class II equipmentis required to meet MIL-DTL-901E standards for shock resistance, but it can do this using flexible mounting parts when installed in the appropriate ship position.
  • Class IIIincludes any device with multiple potential configurations that can be installed both with and without hardware. It must therefore comply with both Class I and Class II requirements.

Whether you are testing missiles, generators, radio equipment, gauges, storage ships, or any other ship system or component, EUROLAB will provide you with a comprehensive, shock-testing program that complies with your program, in accordance with the MIL-DTL-901E standard.

Types of Ship Shock Test

  • Type A testrequires testing for main units. This includes devices that are directly supported by the ship's structure or foundations, piping systems, channel work, or other systems. The purpose of these tests is to ensure that the item has sufficient stiffness and mass against impacts when installed in its proper place.
  • Type B testmeasures the shock response of auxiliary components such as ship power supply sections, diesel engines or electric motors of a larger device.
  • Type C testis performed on subassembly components that are significantly affected by shocks for the main or auxiliary components but are unlikely to affect them in return. This may include thermometers, resistors, counters and other small parts.

EUROLAB performs shock test, medium weight shock test and heavy shock test on light ship. Special shock test machines are required to perform light and medium-weight shock tests per MIL-DTL-901E tests, while heavy shock tests require barge testing with ammunition.
