Abstract:

Particle impact noise detection (PIND) test is a kind of reliability screening technique which is used to detect free particle in hermetical components and is specified in MIL-STD-883E method 2020.7. Some test conditions are specified that aren't always appropriate in practice. This paper derives test conditions of PIND based on dynamics, and obtains the upper limit frequency expression, and analyzes how do vibration acceleration, vibration frequency, recovery coefficient, particle mass and cavity height influence the particle's output energy, and explains the applied range of test conditions in MIL-STD-883E method 2020.7, and derives the best vibration frequency by analyzing the relation between the output power of vibrator and one of he particle under the constant acceleration. Some experiments and simulations are given last.
