Vibration absorbers are devices designed to reduce or eliminate unwanted vibrations in structures and machinery. They work by using a mass-spring system that absorbs energy from vibrations, preventing them from spreading through the material. This helps improve the performance and longevity of equipment, making it essential in various applications, including automotive and aerospace engineering. These devices can be passive or active. Passive vibration absorbers rely on their design and materials to dampen vibrations, while active ones use sensors and actuators to adjust in real-time. Common examples include tuned mass dampers and dynamic vibration absorbers, which are often used in buildings and bridges to enhance stability.
