RTCA DO160 Vibration Test-JOEO Shaker Equipment

MIL-STD-810 vibration test and DO160 vibration testing provide a unified test method and evaluation criteria for the verification of server stress resistance. These standards are widely used in the military, aerospace and industrial sectors and are an important basis for ensuring the reliability of critical systems. These standards are designed to rigorously stress test servers by simulating extreme environmental conditions such as vibration, shock, temperature changes, etc., to ensure that they can maintain stable operation under harsh operating environments.

DO 160 common test program

• Temperature and altitude
• Temperature variation
• Humidity
• Operational impact and collision safety
• Vibrations
• Salt fog
• Dust

In this article, we will briefly introduce vibration testing in the DO 160 standard

DO160 Vibration Test Overview

According to the DO-160 standard, airborne equipment is required to undergo a series of vibration tests to demonstrate that the equipment can maintain established performance and durability indicators at the vibration levels faced by its specific installation location

Standard vibration test (Class S) : Standard vibration test is suitable for fixed wing aircraft. The test shows that the equipment will meet its functional performance requirements in a vibration environment. Vibration environment is the environment experienced by aircraft under normal operating conditions.

Strong vibration test: Strong vibration test determines whether the equipment can operate normally when it is subjected to vibration. It also determines whether the device will continue to function properly after being subjected to durable vibration levels. These vibration tests combine the demonstration of functional performance and structural integrity of the equipment.

Class R: fixed-wing aircraft or helicopters
Class U: Helicopter
U2 Class: Helicopter

High level and short time vibration test: During the engine fan blade damage, fixed-wing aircraft will encounter high level and short time transient vibration when there is abnormal vibration. The test shall be applied to equipment where loss of functional performance may have a serious impact on aircraft performance.

Category H: Tests for fixed-wing aircraft. This test is a universal test that covers all applications. Devices that fit this description must pass the RTCA-DO160 vibration test.

Class Z: Tests for fixed-wing aircraft. Testing for limited low fan frequency applications. Devices that fit this description must pass the RTCA-DO160 vibration test.
The specific testing of the device and the duration of the test depends on the type of aircraft, the location of the device within the aircraft, and the distance of the device from the engine.

Conclusion

The DO-160 is very similar to the tests in MIL-STD-810, however, the DO160 vibration test is specifically designed to evaluate rugged computers expected to operate in or on general aviation aircraft, helicopters, jumbo jets, or supersonic transport aircraft.
