What is the difference between damping vibration isolators and spring vibration isolators?

2025-12-04

• Damping vibration isolators mainly use damping materials or structures to hinder the relative motion of objects, converting mechanical energy into thermal energy or other forms of energy that can be dissipated, thereby reducing vibration.
• Spring vibration isolators utilize the elastic properties of springs to absorb and disperse energy. When subjected to external impact or vibration, the spring will compress or expand, thereby absorbing energy and reducing the vibration transmitted to the structure.

　　2. Application areas:

• Damping vibration isolators are widely used in various situations that require reducing vibration and impact, such as automobiles, building structures, machine parts, etc. Especially in systems that require precise control of vibration, such as high-precision machine tools, optical equipment, etc., the effect of damping vibration isolators is more significant.
• Spring vibration isolators are commonly used in suspension systems of vehicles such as cars, trains, and subways, as well as in vibration isolation of small devices such as consumer electronics. It buffers and disperses forces through the elasticity of springs, protecting equipment and improving ride comfort.
   

• The advantage of damping vibration isolators is that they can effectively reduce mechanical vibration and impact, provide a smooth operating environment, and have a long service life and reliable performance. However, it may require more precise adjustments and maintenance.
• The advantage of spring vibration isolators is that they can more effectively disperse forces, prevent equipment or appliances from being damaged, and have a relatively simple structure and lower cost. However, spring vibration isolators may not be as effective in isolating high-frequency vibrations as damping vibration isolators in certain situations.
