Volant d'inertie : un dispositif mécanique essentiel pour le stockage et la stabilité de l'énergie

Déc 6, 2024

A volant d'inertie is a mechanical device used to store rotational energy. It consists of a heavy wheel or disc that uses cast iron sand casting processes and is mounted on an axle anddesigned to resist changes in its rotational speed.

Key components of a flywheel

1. Wheel/Disc: The primary component of a flywheel, typically made of a dense and durable material such as steel or cast iron. It has a large diameter and a significant mass, providing inertia and storing rotational energy.

2. Axle: The central shaft on which the flywheel rotates. It is connected to the wheel and allows the transfer of rotational energy.

3. Flywheel Ring: Some flywheels have a ring attached to the wheel’s circumference. The ring may have teeth or magnets for specific applications, such as engaging with a starter motor or generating electricity.

4. Mounting: The flywheel is securely attached to an engine or machine’s crankshaft using bolts or other fastening mechanisms.

How a flywheel works

1. Energy Storage: When energy is supplied to the flywheel, typically through an engine or a motor, it starts rotating, building up kinetic energy.

2. Inertia: Due to its mass and rotational speed, the flywheel exhibits high inertia, resisting changes in its rotation. This property allows it to store energy as rotational kinetic energy.

3. Energy Release: When the system requires energy, such as during a power shortage or when additional force is needed, the stored energy in the flywheel can be harnessed and transferred to the connected system.

4. Stabilization: In systems where variations in rotational speed are undesirable, such as internal combustion engines, the flywheel helps smooth out the rotational motion, reducing vibrations and maintaining a more constant speed.

5. Power Regulation: In some applications, the flywheel can act as a governor, regulating the power output or maintaining a constant speed in response to changing load conditions.
