| 摘 要： | 对于弹性安装的机器来说，其自由源速度的测量十分重要，可作为结构声源“强度”来看待。在此对一个排气风扇４个支撑点的６个自由度（３个平动和３个转动）的自由源速度进行了测量，并对测量结果进行了分析和比较。

| Abstract: | To the resiliently mounted machines,the measurement of free source velocities is very
important,which can be regarded as thestrength of structural sound source.In this paper,the
measurements of free source velocities for six degrees of freedom are conducted at four support
points on a ventilation fan,and also the analyses and comparisons of the measured results are
couducted. |
