当初曾google过,忘记从那裡整过来的
What is the difference between a vibration isolator and a vibration damper?
A good vibration isolator lowers the natural frequency of a system to below the excitation (or disturbing) frequency. Keeping these two frequencies "out of sync" greatly reduces the problems of vibration. A good vibration damper takes mechanical energy out of the system. Properly designed metal springs and rubber mounts can be good isolators but have almost no damping capability. Oil dampers (dashpots) have good damping capability but no isolation capability.
Foam products can be good isolators but have limited life.
What is the difference between a vibration absorber and a vibration isolator?
Vibration absorber is a spring mass system attached to the main vibratory system to absorb the vibrations whereas vibration isolators are material like cork , rubber, felt, pad etc. which are used to isolate machines from its foundation and support. These vibration isolation absorb the shocks forces set up in the machinery and prevents the damage of foundations and supports.
h主任说的是
个人以为基本上都是隔振(隔离振动),只是要隔离外来的振动或物体自身的振动,所用的手段不同,所以使用不同的词!
重点应该注意振动源及路径
