Random vibration test requirements for vibration shakers

The requirements for random vibration testing are defined by the frequency-acceleration power spectral density (PSD for short) curve and its tolerance range. Therefore, in addition to meeting the basic requirements of a sinusoidal vibration shaker, a random vibration shaker has several specific technical specifications.

Functions and requirements of vibration test system horizontal table

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.
