模态激振器相关问题

The trunnion is a very important component of the shaker system. It is the U shaped support base that supports the electrodynamic shaker body itself. The shaker trunnion allows the shaker to be rotated in place and provides convenient mounting holes for hanging from a lateral excitation stand, for example the 2050A shaker stand. Without a trunnion, it is very difficult to set up a shaker for modal testing. The trunnion allows the shaker to be configured in different skewed orientations and angles for excitation. Skewing the input force can be particularly important for exciting structures with vertical and lateral modes that are highly uncoupled. The trunnion is also beneficial when aligning the shaker to the structure for modal testing.

耳轴是激振器系统的非常重要的部件。它是“U”形支撑座,支撑电磁激振器台体本身。耳轴允许激振器在适当的位置进行转动,并且为了从横向激励支架上挂起来,提供了方便的安装孔。耳轴允许激振器按照不同的倾斜方向以及角度安装进行激励。对于激励带有高度不相耦合的垂直和水平模态的结构,使输入力倾斜是特别重要的。对模态测试,当激振器跟结构对中时,耳轴也同样是有益处的。
