Summary: This standard specifies the GB/T 2423 in Test Fc sine, random tests Fh Fi mixed mode and test mode, three steady vibration vibration test method to choose the guide. Chapter 4 briefly describes these various steady state vibration test methods and their purpose. This section does not include transient vibration test methods. During the vibration test, you should understand the environmental conditions, in particular sample dynamic environment. This section will help environmental conditions the collection of information (see Chapter 8) and the dynamic environment of estimated or measured (see Chapter 6), and an example demonstrates how to determine the most appropriate vibration test methods. Starting from the vibration conditions, given the selection of the appropriate test methods. Since the actual vibration environment, the random feature is usually dominant effect, so random vibration test to be the most commonly used method. See Chapter 7 Table 1. The following test method can be used for testing before, during and after the vibration response of the sample inspection. How to choose the right incentive methods, see Chapter 8 and Table 2. In this section, the relevant specification writers can find information about the vibration test methods and how to select vibration test method guidelines. For a test method test parameters or severity levels, should refer to the relevant norms.
