| 摘 要： | 冲击载荷识别中,识别频段的确定直接影响识别精度,根据目前确定信号频段的4种方法,通过分析比较,提出了依实际情况,经载荷频段预估、试识别、平滑处理,而后用载荷频谱函数下降20db确定载荷频段的方法,并通过实例,进一步说明了该方法的可行性。

| Abstract: | In impulse load identification, load frequency band influences the identification precision directly. Based on current four methods used to determine the signal frequency band, through analysis and comparison, the method is set up after estimating, trying and smoothing, to deter- mine the load frequency band by reducing the load frequency spectrum by 20dB according to real conditions. The method is proved available by experiment. |
