Dynamic vibration absorbers are devices designed to reduce unwanted vibrations in structures or machinery. They work by using a secondary mass and spring system that absorbs specific frequencies of vibration, effectively minimizing the impact of those vibrations on the primary system. This helps improve the performance and longevity of equipment. These absorbers are commonly used in various applications, including automobiles, buildings, and industrial machinery. By tuning the absorber to match the frequency of the vibrations, they can significantly enhance stability and comfort, making them an essential tool in engineering and design.
