This part of GB/T 2423 provides the standard test method for random vibration, which is used to determine the ability of the sample to resist dynamic loads under the premise that there is no unacceptable functional degradation and (or) the compliance of the overall structure under the specified random vibration test. ability. Broadband random vibration can be used to identify stress accumulation effects and degradation of specific functions. This information, combined with relevant specifications, can be used to assess the acceptability of samples. This standard is applicable to samples that may be subjected to random vibrations in a transport or working environment, such as in aircraft, spacecraft and land vehicles. It is mainly used for samples that are not packaged, and their packaging is part of the sample itself during transport. sample. However, for packaged samples, the sample together with its packaging is considered a sample. For the test of packaged samples, this part can be used together with GB/T 2423.43-2008.
