Making the seas calmer – testing anti-roll systems in boats

Dytran Triaxial Accelerometer Application

Making the Seas Calmer!

 In one application, Dytran’s 3583BT triaxial accelerometer is used to test vibration measurements in anti-roll gyro stabilisation systems for commercial and recreational boats.

Firstly, these systems use gyroscope and flywheel technology to act as a counterbalance to marine turbulence. Secondly, the systems automatically gauge the ocean’s state and reacts instantaneously to turbulence by activating the flywheel.  Which can spin at speeds of up to 896km per hour, generating enough force to stop a boat from rolling.

Thirdly, the precision of Dytran’s 3583BT’s 500mV/g sensitivity range allows it detect vibration levels when the gyroscope and flywheel technologies of the anti-roll system are engaged.  Therefore, making sure the system’s vibrations are within normal limits and don’t contribute to a ship’s overall vibration signature.

Finally, these systems greatly reduce the boats’ roll and provide a smooth ride and calm sailing experience.

In conclusion, the 3583BT is an IEPE triaxial accelerometer that incorporates miniature ceramic shear mode sensing elements, mounted to a single support and packaged in a welded titanium housing for a total weight of 27 grams.

Applications include:

  • Modal and structural analysis
  • Noise, Vibration and Harshness (NVH)
  • Squeak & Rattle
  • Vibration control
  • General purpose triaxial vibration measurements
