| Abstract: | This paper introduces the necessity of vibration test and describes the fixed-frequency sinusoidal vibration test and swept sine vibration test. Mainly introduces the sweep sine vibration test, the formula of the sweep rate, the octave number, the number of stress cycles, the sweep time is derived, and through a specific example of the sweep, the calculation of the relevant parameters has been described. |
