橡胶隔振垫与橡胶减振器的区别DiffeREnce between rubber vibration isolation pad and rubber shock absorber

橡胶隔振垫与橡胶减振器有哪些区别？橡胶隔振垫之所以应用广泛，是因为它具有持久的高弹性，有良好的隔振、隔冲和隔声的性能；造型和压制方便，可自由地选择形状和尺寸，以满足刚度和强度的要求；具有一定的阻尼性能，可以吸收机械能量，对高频振动能量的吸收尤为突出；由于橡胶材料和金属表面间能牢固地粘接，因此不但易于制造安装，而且还可以利用多层叠加减小刚度，改变其频率范围，价格低廉。

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.

当然，与橡胶减振器一样，橡胶隔振垫也有它的弱点，如易受温度、油质、臭氧、日光及化学溶剂侵蚀，造成性能变化及老化，易松弛，因此寿命一般约为8年，但无以上侵蚀寿命可超过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.

橡胶隔振垫的性能不但与橡胶垫的形状及配方有关，还与橡胶的硬度有关，硬度高，刚度大，承载大，硬度低，刚度低，承载小。有些橡胶减振垫的硬度分40℃、60℃、90℃多种，选用时务必注意。

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.

橡胶减震器的优缺点

1.它可以制成各种形状和不同硬度的制品，具有良好的弹性和足够的强度；

2.可使隔振系统的固有频率做的较低，并且具有较高的阻尼；

3.无论在拉、压、剪切和扭转受力情况下，变形都比较大。

和金属弹簧弹簧减震器相比，其主要缺点为：

1.其固有频率难以做到5Hz以下；

2.其抗环境污染与抗温变化能力较弱，寿命较短。

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.
