一、海绵乳胶等材料隔振系统的高频传递特性 海绵乳胶、玻璃纤维和一般天然橡胶是工业上常用的隔振材料。为了了解这些材料的隔振性能,我们对这些材料的块状形体在厚度方向进行了垂直振动的绝对传递率试验。试验表明,这些材料——荷重隔振系统在大于系统共振频率的高频段上,其表征系统隔振性能的绝对传递率比共振绝对传递率相同的简单系统的相应绝对传递率要高。这里,简单系统是指参数为常数的弹簧和粘性阻尼器并联组成的系统。试验的部分结果画 First, sponge latex and other materials high-frequency vibration isolation system transmission properties sponge latex, glass fiber and general natural rubber is commonly used in industrial vibration isolation materials. In order to understand the vibration isolation properties of these materials, we tested the absolute transmissibility of vertical vibrations in the thickness direction of the massive bodies of these materials. The experimental results show that the absolute transmissibility of these systems is higher than that of a simple system with the same resonance absolute transmissibility at high frequencies above the system resonant frequency. Here, a simple system refers to a system of springs and viscous dampers paralleled with constants. Part of the results of the test draw
