本文提出了利用多点巡回采样信号合成的混合谱分析方法,以解决由于采样率限制而难以识别高频信号的问题.本方法尤其适用于旋转件振动的信号处理,模拟算例和真实试验结果都验证了方法的可行性.
In this paper, a hybrid spectrum analysis method based on multi-point tour sampling is proposed to solve the problem that it is difficult to identify high-frequency signals due to the limitation of sampling rate.This method is especially suitable for signal processing of vibration of rotating parts, simulation examples and real test results Have verified the feasibility of the method.
