When designing and applying vibration isolators, the following factors must be considered:

① can provide the required vibration isolation;

② can withstand the specified load;

③ can withstand changes in temperature and other environmental conditions (humidity, corrosive fluid, etc.);

④ It has certain vibration isolation characteristics;

⑤Meet the requirements of the weight and volume of the vibration isolator for the equipment using the vibration isolator.

When the excitation frequency is lower than the natural frequency of the mass (equipment) spring system, the vibration isolator does not have a vibration isolation effect; when the excitation frequency is close to the natural frequency, the vibration will be amplified; only when the excitation frequency is greater than the natural frequency, the isolation The vibrator has vibration isolation effect. It is usually required that the excitation frequency is greater than 2 to 3 times the natural frequency in order to obtain a good vibration isolation effect. For a viscous damping single-degree-of-freedom vibration isolation system, when damping is neglected, K is the force of the vibration isolator in the natural frequency formula, and m is the lumped mass above the vibration isolator. When the static compression δst of the vibration isolator is proportional to the load, such as a steel spring, the natural frequency; the unit of δst is meter.

The natural frequency of rubber isolators is often higher than the above formula. The research of metal rubber technology aims to use metal wire as raw material to develop an elastic porous material, which can be used to prepare metal rubber components with special properties. Metal rubber components are made of metal wires and do not contain any ordinary rubber, but they have the same elasticity and porosity as rubber. They are especially suitable for solving high and low temperature, large temperature differences, high pressure, high vacuum, strong radiation, severe vibration and corrosion. Difficult problems such as damping and vibration reduction, filtering, sealing, throttling and sound absorption and noise reduction under the damping can be prepared in various structural shapes according to different working conditions. Moreover, it has the characteristics of long storage, long service life and no aging phenomenon. It is the best substitute for ordinary rubber under special working conditions of aerospace, national defense weapons and equipment and civilian products.
1. Using metal wire as raw material, it does not contain any ordinary rubber, but it has the same elasticity and porosity as rubber.
2. Resistance to high and low temperature, large temperature difference, high vacuum, strong radiation and corrosive environment.
3. High carrying capacity, fatigue resistance, no aging phenomenon, long service life and storage time.
4. It can meet the needs of damping, vibration reduction, sealing, filtering, throttling and sound absorption and noise reduction. It is the best substitute for ordinary rubber products and other porous material products under special industrial and mining.
5. Its performance indicators can be designed, and by changing different process parameters and methods, metal rubber products with different structural sizes and performance characteristics can be prepared.
6. It is suitable for various fields such as aerospace, missile ship and starship, national defense weapon equipment, petrochemical industry and automobile industry, and has the distinctive features of both military and civilian use. From equipment weighing hundreds of tons to lightweight precision instruments, steel spring isolators can be applied. They are usually used where static compression is greater than 5 cm or where temperature and other environmental conditions do not allow the use of rubber and other materials. The advantages of this type of vibration isolator are:

① Large static compression, low natural frequency, and good low frequency vibration isolation;

② Resistance to corrosion by oil, water and solvents, and not affected by temperature changes;

③ No aging or creep;

④The characteristics change little when mass production.
