Spring dampers are mechanical devices that combine the properties of springs and dampers to control vibrations and oscillations in various systems. They work by absorbing energy from movements, helping to stabilize structures and reduce noise. Commonly used in vehicles, machinery, and buildings, spring dampers enhance comfort and safety by minimizing the impact of shocks and vibrations. These devices typically consist of a spring that compresses or stretches in response to forces, along with a damping mechanism that slows down the movement. The combination allows for effective energy dissipation, making spring dampers essential in applications like automotive suspension and seismic protection for buildings.
