Zusammenfassung:Particle impact noise detection (PIND) is a reliable screening technique specified by MIL-STD-883E. But MIL-STD-883E gives some test conditions which are not always appropriate. The test conditions of PIND are derived here based on dynamics. The upper limit frequency expression is obtained by a transforming equation. How vibration acceleration, vibration frequency, recovery coefficient, particle mass, and cavity height influence the particle's output energy is discussed. Moreover, the applicable range of test conditions of MIL-STD-883E are indicated and the best vibration frequency is derived by analyzing the relationship between the output power of vibrator and the particle's output energy. Some experiments are given.
