3-axis Control

Shorten test time with triaxial control

Replicate the operational environment of your device by running a vibration test in the three linear directions simultaneously. The VibrationVIEW software supports 3 control loops for a Sine, Random, Shock, or Field Data Replication test.

3-Axis Vibration Test

Three-axis testing is accomplished by running a vibration test along three axes using identical or individualized test profiles. The VibrationVIEW software supports different profiles for random vibration tests, and the test systems are compatible with all servo-hydraulic and electrodynamic shakers.

VR Control Systems

A multi-loop test requires one VR9500 per control loop or a VR10500 with multiple loops enabled. Each VR9500 requires the necessary VibrationVIEW software and includes one method of control. The primary VR10500 controller must drive all outputs, but the system can have stacked controllers for more than 16 inputs (up to 512).

The Sine, Random, Shock, and Field Data Replication (FDR) test modes can run 2, 3, or 4 output drive loops simultaneously, but they have different control capabilities on the VR10500.


VibrationVIEW Sine on Random logoRandom
Run random tests with Gaussian amplitude distribution.

  • 104,000 lines of control (26,000 with the VR9500)
  • Supports over 9,999 breakpoints, suitable for virtually any test specification
  • Each control loop can have a unique test profile and limits
  • Includes independent, magnitude and phase, magnitude-only, and equal outputs control
  • “Run For” schedule level can have an independent modifier

VibrationVIEW FDR logoField Data Replication
Playback a recorded time-history file as a control reference; the output phase is synchronized.

VibrationVIEW Sine logoSine
Run a single frequency sine tone at a defined amplitude and time.

  • Each control loop must have the same test profile, but the user can adjust the phase angle between the two outputs (±360 degrees)
  • Control how fast the phase control loop updates in Magnitude and phase control
  • Limit how fast the phase between the output channels changes
  • Includes magnitude and phase, magnitude-only, and equal outputs control
  • Note: Multi-loop Sine is available with the VR10500 only

Run an industry-standard pulse or a user-defined transient pulse; the output phase is synchronized.


Graph settings include a control loop section, and the user can select which control loop demand, control, tolerance, and abort traces to plot. Any loop can be the reference for the transmissibility plot.

Faster & More Realistic

In most operational environments, vibration occurs in the x, y, and z directions. In many industries, engineers must run a test in the three axes simultaneously for a more realistic response. A device under test may pass a sequential, single-axis test but fail a multi-axis test of the same time duration.

Three-axis testing also eliminates the need to remount the device under test for each axis. For a single-axis test, the engineer runs the test profile along one axis at a time. With a triaxial shaker, they can test products along multiple axes at once.
