隔离一般机械振动、瞬态冲击和高频结构噪声的隔振器材种类凡多.主要应用有各种橡胶器材、金属弹簧、空气弹簧、软木、毛毡以及泡沫海棉与粘弹性材料等等.目前普遍选择的是橡胶和金属弹簧两种隔振器材,粘弹性材料及其结构也正在扩大应用.天然橡胶和许多人工合成橡胶具有良好的弹性和适当的阻尼,并能同金属牢固地粘接(常温粘接强度大于30公斤/厘米~2,有的大于54公斤/厘米~2).故可根据不同的弹性(弹性决定频率特性)与阻尼要求制成各种结构类型的隔振器材.不过,一般橡胶隔振器的最低固有频率只能做到5赫.此外,一些环境因素影响到橡胶的性能和寿命,但能人为加以补救,使用寿命可到5～7年乃至10年.
Isolation of general mechanical vibration, transient impact and high-frequency structural noise, vibration and other types of equipment Fan. The main application of a variety of rubber equipment, metal springs, air springs, cork, blankets and foam sponge and viscoelastic materials, etc. Currently A common choice is rubber and metal spring two kinds of vibration isolation equipment, viscoelastic material and its structure is also expanding the application of natural rubber and many synthetic rubber with good flexibility and appropriate damping, and can be firmly bonded with the metal ( At room temperature adhesive strength greater than 30 kg / cm ~ 2, and some more than 54 kg / cm ~ 2). So it can be made according to different flexibility (flexibility to determine the frequency characteristics) and damping requirements made of various types of vibration isolation equipment. , The lowest natural frequency of rubber vibration isolators can only reach 5 Hertz.In addition, some environmental factors affect the performance and life of rubber, but can be artificially remedied, the service life of up to 5 to 7 years or even 10 years.
