vibration damper working principle

A vibration damper, also known as a harmonic balancer, is a device used to reduce or eliminate unwanted vibrations in mechanical systems. Here's a basic overview of its working principle:

Vibrations damper

1. Absorption of Vibrations:

The damper consists of a mass (often a heavy ring) connected to a flexible material such as rubber or a viscous fluid. This mass is designed to absorb and dissipate vibrational energy.

2. Counteracting Vibrations:

When the system vibrates, the damper's mass moves out of phase with the vibrations. This movement creates a counteracting force that dampens the vibrations.

3. Dissipation of Energy:

The flexible material or fluid in the damper converts the vibrational energy into heat, which is then dissipated.

4. Harmonic Control:

By tuning the damper to specific frequencies, it can effectively counteract harmonic vibrations, which are repetitive and periodic, reducing the overall stress on the mechanical system.

This principle is commonly used in automotive engines, rotating machinery, and other systems where controlling vibrations is crucial for performance and longevity.
