摘要
结合液压泵降噪实践对液压泵噪声的统计分析和试验研究作简要述评.指出"液压泵噪声的统计分析及频谱测试"为估算同类液压泵噪声总级并估计其频率分布提供了简便有效方法,为正确设计液压系统使其工作在低噪声工况提供了依据;对"低噪声液压泵"的选型和液压泵降噪措施的发展有益.
The statistic analysis and experimental investigation of hydraulic pump＇s noise are introduced. It provides a effective method for estimating the sound levels and frequency distribution of hydraulic pump＇s noise.The oil hydraulic system can be proper designed for low noise operating mode. It＇s useful for developing of the quiet hydraulic pump.
