3 Axis Electrodynamic Shaker

The solution to the limit of single axis vibration testing is the 3-axis electrodynamic vibration test system from Dongling.  Three shakers are mounted to a single base and sharing a single table on which to mount the test article. One shaker is mounted in the X axis, one in the Y axis and one in the Z axis. With this electrodynamic 3-axis vibration test system vibration tests can be performed in all three axis’ simultaneously. The only way this test system can work to the test requirements you demand is with the hydraulic orthogonal decoupling bearings adopted for connecting the vibration shakers with the table. This industry leading solution can provide a reliable motion and working environment for a more realistic simulation environment and reduced test time. 3-axis vibration testing is being performed in several countries and can reach frequencies up to 2000 Hz.

[3 Axis Electrodynamic Shaker - Multi Axis Shaker]

The Dongling Technologies 3 axis vibration test system is the industry leading 3 axis shaker test system and provides the ability to execute a more realistic vibration test. When the test laboratory is limited by single axis shakers, 3 axis testing can only be achieved by running the test in a single axis and then rotating the test article in each of the other 2 axis’ and running the test 2 more times. The real world environment is closer to simultaneous vibration in the X,Y and Z axis’ in combination. 3 Axis vibration test equipment from Dongling Technologies is in use in laboratories around the world.


  • Reduced test time: testing in 3 axis simultaneously can shorten the total test time due to reduced set up time.
  • Reproduce real world environment more accurately.
  • Usable frequency range of up to 2000 Hz or even more. Proven with multiple installed systems.
  • Interlock protection: this safety feature is designed into the system and provides protection in the event that there is a malfunction in any one of the 3 shakers. If that occurs the 2 remaining shakers will stop and thus protect the shakers and the test article.
