Many products are subjected to vibration tests in three mutually perpendicular directions of x, y, and z. Small test pieces can be used to change the fixture installation state and use the fixture to flip to achieve three directions of vibration on the vertical vibration table. For large specimens, using the fixture flip method may cause excessive eccentric torque, and the vibration test of some special products (such as gyroscopes, etc.) requires that the installation state of the main shaft and the relative position of the earth remain unchanged, and it is not possible to change the fixture.
