直升机GT-2A航空重力仪减振系统振动分析

Testing and analysis for GT-2A airborne gravimeter vibration reduction system in a helicopter

国内首次开展高分辨率直升机航空重力在内陆丘陵地区采用低速、低空起伏飞行的方式执行测量任务。航空重力减振系统面对全新的直升机搭载平台和飞行环境,关于减振系统的很多技术问题需要得到解答。因此,笔者开展针对直升机航空重力减振系统振动加速度的数据采集和测试工作,获得的试验结果为今后航空重力减振系统的设计、安装与监测提供借鉴依据。

China’s first high-resolution helicopter airborne gravity measuring task adopted low-speed and low-altitude on drape flight.Airborne gravity vibration reduction system is faced with the new helicopter flight platform and flight environment,and a lot of problems concerning the damping system should be resolved. Therefore,the authors conducted data collection and testing for the helicopter airborne gravity vibration reduction system,and the test results obtained can provide the reference basis for the future airborne gravity vibration system design,installation and monitoring.
