A mechanical damper is a device that is used to reduce the effects of vibrations and oscillations in a mechanical system. It works by absorbing energy from the system, dissipating it, and reducing the amplitude of the vibrations. Mechanical dampers are used in a variety of applications, such as automotive suspension systems, building structures, and aircraft components. They are also used in industrial machines, like pumps and compressors, to reduce noise and vibration. Mechanical dampers are designed to be highly efficient, meaning they can absorb a large amount of energy without causing any significant changes to the system. This makes them ideal for controlling vibrations in sensitive systems, such as medical equipment or precision instruments.
