弹簧减振器和金属减振器一样吗？Is spring shock absorber the same as metal shock absorber?

    如果说弹簧减振器就是金属减振器，我想很多人还会犹豫下，其实从材质上讲，弹簧减振器主要材质还是以金属为主，所以也可以说弹簧减振器属于金属减振器，但只是其中一种。金属减振器其实包含很多类型的减振器，那具体是怎样呢？ 　　

If the spring damper is a metal shock absorber, I think many people will hesitate. In fact, from the material point of view, the main material of the spring shock absorber is still metal, so it can be said that the spring shock absorber belongs to metal shock absorber, but it is only one of them. Metal shock absorbers actually contain many types of shock absorbers. What aRE the details?

    在减振器行内中，却是很多人都会把弹簧减振器直接说成金属减振器，事实上也是可以这么说，因为如今金属减振器大部分都是以弹簧为主的结构设计，只是在一些不同环境中会改变其外形，于是称呼会被修改不会称为弹簧减振器，而是某某减振器。

In the shock absorber industry, however, many people will directly refer to the spring shock absorber as the metal shock absorber. In fact, it can also be said, because most of the metal shock absorbers are spring based structural design, but their shape will be changed in some different environments, so the name will be modified, not called spring damper, but so and so shock absorber.

　  金属减振器的优点：静态压缩量大，固有频率低，低频隔振良好；、耐受油、水和溶剂等侵蚀，不受温度变化的影响；、不会老化或蠕变；、大量生产时特性变化很小。金属减振器的缺点：本身阻尼极小（阻尼比约0.005），以致共振时传递率非常大。 

Advantages of metal shock absorber: large static compression capacity, low natural frequency, good low frequency vibration isolation; resistance to corrosion of oil, water and solvent, not affected by temperature change; no aging or creep; small change in characteristics during mass production. The disadvantage of metal shock absorber is that its damping is very small (damping ratio is about 0.005), so that the transmissibility is very high at resonance.

　　高频时容易沿钢丝传递振动；容易产生摇摆运动，因而常须加上外阻尼（如金属丝、橡胶、毛毡等）和惰性块。从上面可以看出金属减振器的优缺点跟弹簧的优缺点是一模一样，这样就可以推断，弹簧减振器是属于金属减振器。

It is easy to transmit vibration along the steel wire at high frequency, and swing motion is easy to occur, so external damping (such as metal wire, rubber, felt, etc.) and inert BLOCK are often added. As like as two peas, the advantages and disadvantages of metal dampers are identical with the advantages and disadvantages of springs.
