Design of mechanical environmental monitoring system for satellite powered-flight phase
摘要
Abstract
To obtain the acceleration and force of satellite-rocket interface for satellite powered-flight phase accurately,a mechanical environmental monitoring system was designed.The system is composed of vibration monitoring unit,vibration sensors and strain gauges.The vibration monitoring unit was with three operating modes:powered-flight phase measurement mode,on-orbit vibration data analysis mode,and vibration data transmission mode.It adopts strain-based dynamic load identification technology on the satellite-rocket interface,enabling data acquisition from 6 channels of vibration mechanical sensors and 24 channels of strain data.The ground test shows that the vibration measurement accuracy of the system reaches 10%,and the maximum error between the strain measurement and the strain data collected by the LMS(LabVIEW Measurement Studio)system is less than 4%.The measurement results of the mechanical environment of the powered-flight phase on board may provide a reference for optimizing the satellite analysis model and improving the simulation conditions for the satellite ground mechanical environment,and provide important technical support for the subsequent development and application of satellites.关键词
