Scope

This part of GB/T 2423 provides the standard test method for random vibration to determine whether the sample is subjected to the specified random vibration test.
The ability to resist dynamic loads without unacceptable functional degradation and/or compliance with the overall structure.
Broadband random vibration can be used to identify cumulative effects of stress and degradation of specific functions. Combining this information with relevant specifications, you can

Summary	This standard specifies the test method for random vibration standards to determine the ability of a sample to withstand dynamic loads without the occurrence of unacceptable functional degradation and/or compliance with the overall structure under the specified random vibration test. Wideband random vibrations can be used to identify stress accumulation effects and degradation of specific functions. This information, combined with relevant specifications, can be used to assess whether a sample is acceptable. This standard applies to samples that may be subject to random vibrations in a transport or work environment, such as in aircraft, spaceships, and land vehicles. It is primarily used for unpackaged samples and as part of the sample itself during transport. sample. However, for a packaged sample, the sample, along with its packaging, is considered a sample. For packed samples
