摘要
航空发动机健康管理器的测试平台主要用于振动信号测试。此平台采用NI设备构建双通道信号输出,对应带高齿的音轮信号和同频率振动信号。同时,测试平台同步采集输出信号,并完成理论计算。采用能量重心法对计算结果进行频谱校正,修正了FFT计算带来的幅值和相位误差。对比分析测试平台和健康管理器的输出结果,验证健康管理器的功能。测试结果表明,测试平台能完整测试和验证健康管理器的振动采集、分析功能。
The test platform for prognostic health device is mainly designed for vibration signal test.The platform adopts NI device to construct dual channels for signal output corresponding to the wheel signal with high teeth and the vibration signal of the same frequency.Meanwhile,two output signals are acquired simultaneously and theoretical computation is completed.Besides,the platform uses the energy centrobaric correction method to modify the frequency and phase errors which are brought by FFT computation.By comparing the output results between the test platform and prognostic health management device,the test platform can completely support the testing and verification for prognostic health device.
