Principle and Function of Dampers


Principle and Function of Dampers

Dampers are commonly used mechanical components that reduce vibration and shock by consuming energy in mechanical systems, protecting machinery and products, and improving productivity and quality. The principle of dampers is to reduce vibration and shock by consuming energy in mechanical systems. Common methods used include friction, liquid or gas resistance.
Friction dampers use friction between two contact surfaces to prevent movement of objects. Hydraulic dampers consume mechanical energy through the viscosity and resistance of liquids to reduce vibration and shock. Gas dampers consume mechanical energy through gas resistance.
Dampers can be divided into various types according to their structure and application, including friction dampers, hydraulic dampers, gas dampers, hydraulic buffers, gas buffers, and rotational dampers. Friction dampers are simple in structure and easy to maintain, but they are prone to wear on the friction surface, susceptible to temperature, and prone to changes in friction force.
Gas buffers generate resistance by compressing gas, but their absorption capacity is poor and their lifespan is short. Hydraulic dampers have the advantages of stable resistance, adjustable damping force, and long lifespan, and are commonly used in machine tools, cranes, and railway vehicles.
Different types of products have different application industries. Hydraulic buffers are widely used in industrial automation, automobile manufacturing, cranes, port machinery, automated warehouses, tire equipment, and blow molding machines to absorb mechanical energy generated by collisions and protect machinery and personnel. Rotational dampers are mainly used in rotating components to slow down rotation speed and improve working lifespan and stability by using the viscous effect of oil. They are currently used in automotive interior and exterior parts, home appliances, 3C digital products, kitchen and bathroom supplies, furniture, and other industries.
