Gyroscopic boat stabilizer

CPGE/Univ

The Gyroscopic Boat Stabilizer is an educational product designed based on the actual system, for teaching industrial engineering sciences.

This educational product is intended for use in CPGE PCSI/PSI - PTSI/PT, TSI and ATS courses.

The stabilizer has:
- a flywheel, controlled in terms of rotation speed (up to 4000 rpm).- an articulated gyroscope support frame, controlled by an electric actuator, with controlled rotation speed to impose a controlled gyroscopic torque. - an articulated overload controlled by an electric actuator, allowing the boat's center of gravity to be modified and a rolling motion to be imposed on it.

The three actuators are equipped with an encoder, and an inertial unit is attached to the articulated frame, enabling the following aspects of the program to be addressed:

  • Servo control (characterization, identification, modeling, correction)
  • Geometric/kinematic law
  • Statics
  • Kinetics/Dynamics/Energy/Power.
  • Process AI

The control software, MyViz, includes:

  • Dashboards tailored to each educational activity
  • An interface for analyzing all measured and calculated signals
  • A digital twin, a 3D model that can be controlled in real time, reflecting the actual dynamics of the system

Educational activities:


TP1: DISCOVERING SYSTEMS
- Analyze the influence of the position of the overload on the boat's behavior
- Analyze the influence of the gyroscope's orientation and speed on the boat's behavior
- Identify the three functional chains

TP2: GEOMETRIC ANALYSIS
- Identify the structural chain for positioning the overload in order to determine the geometric I/O law
- Identify the structural chain for positioning the gyroscope frame in order to determine the geometric I/O law

WP3: SLCI PERFORMANCE AND MODELING
- Propose a behavior model for the various components of the overload movement position control chain and the performance of this control system
- Propose a behavior model for the various components of the speed control chain for the orientation of the flywheel and characterize the performance of this control system

WP4: CORRECTOR
- Choose a corrector based on the open-loop behavior of the gyroscope orientation

TP5: MODELING OF MECHANICAL ACTIONS
- Determine the boat's heel based on the position of the overload in order to deduce the equilibrium orientation of the assembly

TP6: KINETICS
- Determine the equivalent inertia of the power chain associated with the rotational speed of the flywheel

TP7: ENERGY
- Describe the flywheel start-up process that minimizes energy consumption (limited on a boat).

TP8: DYNAMICS, GYROSCOPIC TORQUE
- Study of the gyroscopic effect: determine the relationship between the rotational speed of the flywheel frame and the dynamic behavior of the boat. - Address the issue of electrical energy availability on board a boat: implement a digital artificial intelligence (AI) solution to determine the flywheel start-up procedure.- Address the issue of electrical energy availability on board a boat: implement a numerical artificial intelligence (AI) solution to determine the least energy-intensive flywheel start-up procedure.

The teaching system will be delivered with:

- A technical file with details of geometric, kinematic, and dynamic modeling calculations. - An educational file with written and corrected practical activities. - A Solidworks volumetric model that can be used directly for simulations in Meca3D.- Kinematic diagrams configured for easy use/adaptation in practical activities
