扫描正弦加载的监控加速度计通常用一个加速度计完成。这种方法适合于简单系统的输入监控。然而对于大试件并且支持在支柱、吊架上,则运动输入在所有支承点上不再是相同了。这是因为试件的起始共振引起重心的明显飘移,反过来就引起各个支承点驱动级的偏差和变化。于是用几个加速度计输入的平均值控制,並且调好了,就能得到改进。 A scanning accelerometer with sinusoidal loading is usually done with an accelerometer. This method is suitable for simple system input monitoring. However for large specimens and support on pillars, hangers, the motion input is no longer the same at all points of support. This is because the initial resonance of the specimen causes a significant drift of the center of gravity, which in turn causes variations and variations in the drive stage for each bearing. So with a few accelerometer input average control, and adjust good, can be improved.
