Multiple Electrohydraulic Shakers

You know that in the “real world” vibration is not uniaxial. So you are not satisfied with stopping your test while you take time to change your DUT’s axis (relative to shaker motion) from X, then to Y and finally to Z, three tests. Unfortunately, most shaker systems provide only one axis. Many test engineers have seen nothing else. You need multiple shakers to drive your test platform in multiple axes, so that you can evaluate your products’ ability to withstand earthquakes, to cite one of ebook 14’s examples.
