Wave tank

 

General characteristics: (See image of the TANK).

 

*    Beater: standard float oscillating duck

 

*    Generated swells :

·        Random and regular

·        Period simulated: [0,8 – 2,2 S]

 

*    Revolving plate :

·        Modification of  attack angle  swell on the models

 

*    Shock absorbers :

·        The main thing: ballast out of roller ·

·        Side: the vague parasites absorb due to reflexions on the models tested

 

Instrumentation ·

·        Capacitive probes,

·        Dynamometric balance 6 components ·

·        Incremental position sensors standard LVDT,

·        Accelerometers · Telemeter laser,

·        Acquisition: from 16 to 64 multiplexed ways,

·        Conversion A/D with 100 KHz.

 

 Tests carried out
