橡膠隔振墊與橡膠減振器的區別DiffeREnce between rubber vibration isolation pad and rubber shock absorber

橡膠隔振墊與橡膠減振器有哪些區別？橡膠隔振墊之所以應用廣泛，是因為它具有持久的高彈性，有良好的隔振、隔衝和隔聲的性能；造型和壓製方便，可自由地選擇形狀和尺寸，以滿足剛度和強度的要求；具有一定的阻尼性能，可以吸收機械能量，對高頻振動能量的吸收尤為突出；由於橡膠材料和金屬表面間能牢固地粘接，因此不但易於製造安裝，而且還可以利用多層疊加減小剛度，改變其頻率範圍，價格低廉。

What are the differences between rubber isolation pad and rubber shock absorber? The reason why rubber vibration isolation pad is widely used is that it has long-lasting high elasticity, good vibration isolation, shock isolation and sound insulation performance; it is convenient for modeling and pressing, and can freely choose the shape and size to meet the requirements of stiffness and strength; it has certain damping performance, which can absorb mechanical energy, especially for high-frequency vibration energy; due to rubber material and gold, rubber pad is widely used It is easy to manufacture and install because of the strong adhesion between the surfACEs, and the multi-layer superposition can be used to reduce the stiffness and change the frequency range.

當然，與橡膠減振器一樣，橡膠隔振墊也有它的弱點，如易受溫度、油質、臭氧、日光及化學溶劑侵蝕，造成性能變化及老化，易鬆弛，因此壽命一般約為8年，但無以上侵蝕壽命可超過10年。

Of course, like rubber shock absorbers, rubber vibration isolation pads also have their weaknesses. For example, they are easy to be eroded by temperature, oil quality, ozone, sunlight and chemical solvents, resulting in performance changes and aging, and easy to relax. Therefore, the service life is generally about 8 years, but the service life without the above erosion can exceed 10 years.

橡膠隔振墊的性能不但與橡膠墊的形狀及配方有關，還與橡膠的硬度有關，硬度高，剛度大，承載大，硬度低，剛度低，承載小。有些橡膠減振墊的硬度分40℃、60℃、90℃多種，選用時務必注意。

The performance of rubber vibration isolation pad is not only related to the shape and formula of rubber pad, but also related to the hardness of rubber, with high hardness, high stiffness, large bearing capacity, low hardness, low stiffness and small bearing capacity. The hardness of some rubber damping pads can be divided into 40 ℃, 60 ℃ and 90 ℃, which should be paid attention to when selecting.

橡膠減震器的優缺點

1.它可以製成各種形狀和不同硬度的製品，具有良好的彈性和足夠的強度；

2.可使隔振系統的固有頻率做的較低，並且具有較高的阻尼；

3.無論在拉、壓、剪切和扭轉受力情況下，變形都比較大。

和金屬彈簧彈簧減震器相比，其主要缺點為：

1.其固有頻率難以做到5Hz以下；

2.其抗環境汙染與抗溫變化能力較弱，壽命較短。

Advantages and disadvantages of rubber shock absorber

1. It can be made into products of various shapes and hardness, with good elasticity and sufficient strength;

2. It can make the natural frequency of vibration isolation system lower and have higher damping;

3. No matter under tension, compression, shear and torsion, the deformation is relatively large.

Compared with metal spring shock absorber, its main disadvantages are as follows

1. It is difficult to achieve the natural frequency below 5Hz;

2. Its ability to resist environmental pollution and temperature change is weak, and its service life is short.
