摘要: 介绍了现用的制定声载荷谱的方法,并在使用状态时间进行归纳的过程中解决了针对倍频程或1/3倍频程声压级分析结果进行归纳的具体方法。按这一方法归纳的声疲劳载荷谱及其软件已成功地用于声疲劳试验

关键词: 声疲劳载荷谱, 数据归纳方法

Abstract: The general approach to sonic fatigue test spectrum was discussed at first. A special method based on the measured acoustic data and analysed by one octave band or one third octave band analyser was introduced here. The method was successfully applied to actual sonic fatigue tests.

Key words: sonic fatigue, test spectrum, data generations
