可嵌入式飞行器振动谱测试分析装置电路设计

由于异态振动对小型飞行器导航部件造成很大影响,可通过对飞行器的本体振动谱实施连续的快速反应监测并改变其力学参数来改变.电路设计通过较高Q值的带通滤波器组、交直流变换与频带均值检出、各离散频点相对幅值的量化、多频点量化信号并行输出等,用单片机对多频点量化并行信号与模板进行简单比对判别,发现异态振动时,给出控制信号改变被动...

Circuit design of spectrum test and analysis equipment for embeddable aircraft vibration

Because a small aircraft navigation components can be affected by different states of vibration,through to change the mechanical parameters of the passive solution can change the premise of the mechanical parameters.This design uses a high-Q band-pass filter family,the mean AC and DC transform and band detection,the relative amplitude of each discrete frequency point quantitative,multi-frequency quantization signal parallel output.Subsequently,the MCU can be used in parallel on multi-frequency signal and the template quantify than simple discrimination,found that different states of vibration,is given control signal to change the mechanical parameters of the passive vibration isolation devices to achieve on the aircraft vulnerable parts of the passive vibration isolation navigation purpose.
