MIL-STD-810 Shock and Vibration Testing

Viable Power performs in-house MIL-STD-810 Shock and Vibration Testing (methods 514.8 and 516.8) on our power supplies to meet the specific needs and requirements of our clients. The tests that we perform help ensure the durability and dependability of our ruggedized power supplies when transporting or operating in environments prone to vibration and shock.

We perform these stress tests in accordance with MIL-STD-810 at our in-house testing facility. Our engineers look at several critical things, such as the ability of the circuit boards, transistors, and other power supply components to withstand the damaging effects of vibration and shock.

We perform the following MIL-STD-810 Vibration Testing procedures on our power supplies:

• Procedure I – General Vibration: A test for power supplies that are secured or tied down during transport or will be deployed on a vehicle during their life cycle.
• Procedure III – Large Assembly Transportation: This test looks at big collections of systems that form a large vehicle mass and are transported or installed on tracked or wheeled vehicles. The power supplies are placed on our vibration table and are tested using the profiles described in Annexes C and D.
• Procedure IV – Assembled Aircraft Store Captive Carriage and Free Flight: For power supplies mounted or fixed on an aircraft. The vibration system is used to drive this test through a fixture.

Viable Power tests power supplies using the Transportation and Operational tailoring guidance for vibration exposure definition outlined in Method 514.8 Annexes C and D according to Viable Power’s vibration system capabilities.

The vibration system maximum force rating for Sine and Random is 3,200 lbf, and the frequency range is 2 to 2,500 Hz. The vibration tests can be done in operating and non-operating modes. The vibration system can perform the following vibration profiles: Sine, Random, Sine on Random, and Real Data Acquisition and Playback (RDAP).

The custom military power supplies designed by Viable Power can be tested under five different MIL-STD-810 Shock Testing (516.8) procedures:

• Procedure I – Function Shock: This test observes whether functional damage occurs from shocks and looks at the overall survivability of a system.
• Procedure II – Transportation Shock: Procedure II looks at a power supply’s response to repetitive shocks encountered in ground vehicles and other transportation scenarios.
• Procedure IV – Transit Drop: This test puts a power supply in a transit case and drops it onto a hard surface, and it assesses whether a power supply can withstand an accidental drop during loading and unloading.
• Procedure V – Crash Hazard Shock Test: This test looks at power supplies mounted on ground or air vehicles that could detach during a crash and cause harm to a driver, pilot, or nearby people.
• Procedure VI – Bench Handling: Bench handling assesses power supplies that could experience a shock while stationary on a workbench during repair, maintenance, or packaging.

Viable’s Vibration system capabilities include:

Viable Power manufacturers custom AC-DC power supplies and custom DC-DC power supplies with quick turnaround times for military and civil aviation industries. Not only can we subject our power supplies to the latest MIL-STD-810 shock and vibration test methods, but we can also test them to RTCA-DO-160 and MIL-HDBK-2164A to meet our customers’ requirements. All these tests ensure that our power supplies can withstand the vibration and shock stresses encountered in handling, transportation and service environments while remaining a reliable power source.

If you are looking for a ruggedized power supply that meets specific standards such as MIL-STD-810, MIL-STD-704, MIL-STD-1399 or any other specific standards, please feel free to fill out a request for proposal or contact us directly.
