摘要: 直升机发动机和传动系统是直升机的关键部件，其工作的可靠性直接关系到直升机的飞行安全。因此，对直升机动力装置和传动系统进行振动实时监视是保障直升机飞行安全的重要手段。本文采用FPGA+DSP架构理念，设计开发了直升机振动实时监视系统。通过装机试验，采集直升机关键部位振动结果，其与事后数据分析结果相吻合，解决了在飞行中高采样率振动数据实时监视的难题，有力地保障了直升机飞行安全。本研究结果为后续型号飞行高频数据的实时采集、处理及安全监控提供了技术支撑。Abstract: The engine and the transmission system are the key components of helicopter, and their reliability is directly related to the flight safety of helicopter. Therefore, real-time vibration monitoring of helicopter power plant and transmission system is an important means to ensure helicopter flight safety. This paper adopts FPGA+DSP architecture concept to design and develop a real-time helicopter vibration monitoring system. Through the installation test, the vibration results collected from the key parts of the helicopter are consistent with the results of post-installation data analysis, which solves the difficult problem of real-time monitoring of vibration data with high sampling rate in flight and effectively guarantees the flight safety of helicopter. The research results provide technical support for real-time acquisition, processing and safety monitoring of high-frequency flight data of subsequent models.
