彈簧減振器和金屬減振器一樣嗎？Is spring shock absorber the same as metal shock absorber?

    如果說彈簧減振器就是金屬減振器，我想很多人還會猶豫下，其實從材質上講，彈簧減振器主要材質還是以金屬為主，所以也可以說彈簧減振器屬於金屬減振器，但隻是其中一種。金屬減振器其實包含很多類型的減振器，那具體是怎樣呢？ 　　

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?

    在減振器行內中，卻是很多人都會把彈簧減振器直接說成金屬減振器，事實上也是可以這麼說，因為如今金屬減振器大部分都是以彈簧為主的結構設計，隻是在一些不同環境中會改變其外形，於是稱呼會被修改不會稱為彈簧減振器，而是某某減振器。

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.

　  金屬減振器的優點：靜態壓縮量大，固有頻率低，低頻隔振良好；、耐受油、水和溶劑等侵蝕，不受溫度變化的影響；、不會老化或蠕變；、大量生產時特性變化很小。金屬減振器的缺點：本身阻尼極小（阻尼比約0.005），以緻共振時傳遞率非常大。 

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.

　　高頻時容易沿鋼絲傳遞振動；容易產生搖擺運動，因而常須加上外阻尼（如金屬絲、橡膠、毛氈等）和惰性塊。從上面可以看出金屬減振器的優缺點跟彈簧的優缺點是一模一樣，這樣就可以推斷，彈簧減振器是屬於金屬減振器。

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.
