Dampening systems are mechanisms designed to reduce vibrations and oscillations in various structures and machines. They work by absorbing energy from movements, which helps to stabilize the system and improve performance. Common applications include automobiles, buildings, and bridges, where excessive vibrations can lead to discomfort or structural damage. These systems can be passive or active. Passive dampening systems use materials like rubber or springs to absorb shocks, while active systems employ sensors and motors to counteract vibrations in real-time. Both types are essential for enhancing safety, comfort, and longevity in engineering designs.
