Large static compression, low natural frequency, and good low-frequency vibration isolation 2. The advantages of this type of vibration isolator are 1. 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. 2. Steel Spring Vibration Isolatorįrom equipment weighing hundreds of tons to lightweight precision instruments, steel spring isolators can be applied. It is especially suitable for hostile environments such as aviation, aerospace, navigation, and the chemical industry. They can be made into a variety of vibration isolators and are suitable for vibration damping and isolation of various electronic instruments, power equipment, and pipelines. Vibration damping and vibration isolation components made of metal rubber are characterized by small size and lightweight. Special requirements for component materials. Therefore, various components made of it can not only work in the above-mentioned harsh environment, but also maintain very good properties in this environment, and can meet the special needs of spacecraft for national defense and some special working environments. And the working temperature of natural rubber is -40☌~60☌ and the working temperature of metal rubber is -150☌~+360☌, its advantages are obvious. For example, because the damping material of the bridge damping bearing is made of natural rubber, it is conceivable that the replacement engineering amount and economic loss caused by the failure of aging can be imagined. The metal rubber component has the characteristics of long storage and long service life, and no aging phenomenon. As the magnitude of the external excitation increases, the "natural frequency" of this product decreases, so it has a good vibration isolation effect it can be said that metal rubber is a loose structure material with high elasticity and good damping characteristics, and its density is only metal About 0.3.īecause the metal rubber material can withstand high temperature, high pressure, high vacuum, and ultra-low temperature, it does not evaporate in the space environment and is not afraid of space radiation and particle impact. That is, the effect of gradually softening stiffness appears, which will reduce the "natural frequency" of the system's spatial direction.
Its stiffness characteristic also presents a linear-soft characteristic-hard characteristic non-linear characteristic with increasing amplitude. In the vibration isolation zone, the internal damping decreases rapidly, so it has excellent damping characteristics, with a damping ratio of 0.2 to 0.3.
The damping in the resonance zone is significantly increased, which can effectively suppress the resonance peak. Under the action of alternating stress and strain, a large amount of vibration energy is dissipated. The inside is a network, similar to the macromolecular structure of natural rubber. It is especially suitable for solving high and low temperature, large temperature differences, high pressure, and high vacuum. The metal rubber component is made of metal wire and does not contain any natural rubber, but it has the same elasticity and porosity as natural rubber. Metal rubber is a simulation product of natural rubber. The sturdy handle provides a good grip that lets you move the massager smoothly in any direction.I. Types 1.
