Study of PIND Vibration Detection Conditions for Remainders in Space Relay Based on Curve Fitting Theory
摘要
Abstract
Particle impact noise detection(PIND) is one of the most important methods in detecting remainders within space relays.Theoretical deduction and experimental research are used to study the detection conditions of PIND at present.In this paper,a study method based on curve fitting theory was proposed.Based on the limited experimental data,the detection conditions are taken as input variables,the intensity of the impact sound signal was taken as the output variable.Based on the fitting results,how the parameters of the detection conditions(cavity height,vibration acceleration and frequency) influence the signal intensity was given.关键词
