Multi axis vibration testing is a complex testing method whereby a sample is shaken or excited along more than one axis. Multi axis vibration testing is performed by applying a single-axis vibration to a sample along the X, Y and Z axes of the product. These tests are usually performed using a linear shaker and rotating the sample onto the following axis after each round. Although the single axis shaker is still widely used for vibration testing, latest research has shown that there are some conditions which are not appropriate to be simulated by this equipment.
