针对螺旋桨风机的振动测试，开发并评估了测试程序和安装配置。本文讨论了静态测试程序，并附文讨论了动态测试。扫频正弦、随机噪声和冲击激励都为确定共振频率提供了可接受的结果。扫频正弦激励通常提供最容易解释的加速度信息。为了准确解释加速度数据并正确识别共振频率，有必要获得整个相关频率范围内叶尖加速度随频率变化的曲线图。 为了识别所有可激发共振频率，有必要单独振动所有叶片的前端，并将加速度记录为受激叶片或相邻叶片前端频率的函数。对于一些具有四个以上叶片的风机，可能只能通过测量每个受激叶片前端的振动来识别所有可激共振频率。引文:ASHRAE Transactions，1984年，第90卷，pt。佐治亚州亚特兰大1A

Test procedures and a mounting configuration have been developed and evaluated for the vibration testing of propeller fans. The static testing procedures are discussed in this paper, and a companion paper discusses dynamic testing. Swept sine, random noise, and impact excitation all provide acceptable results for determining the resonance frequencies. Swept sine excitation usually provides acceleration information that is easiest to interpret. In order to accurately interpret the acceleration data and properly identify the resonance frequencies, it is necessary to obtain a plot of the blade tip acceleration as a function of frequency over the entire frequency range of interest. To identify all the excitable resonance frequencies, it is necessary to individually vibrate the leading tips of all blades and record the acceleration as a function of frequency on the leading tip of the excited blade or an adjacent blade. For some fans with more than four blades, it may only be possible to identify all of the excitable resonance frequencies by measuring the vibration of the leading tip of each excited blade.
