一、概述软木是使用最为悠久的隔振材料之一,虽然,由它构成隔振系统的固有频率较高(以下简称软木的固有频率),在应用上受到限制,但因价格低廉、使用方便加之其它性能较好等,故仍用于隔振.软木通常用于受压.与橡胶不同,软木即使压缩量达30%也不会横向凸出.载荷较大时,刚度减少,其静刚度曲线与紫铜相似.软木的最佳受压载荷为5～20吨/米~2 (即0.5～2公斤/厘米~2).软木的阻尼比约为
I. Overview Cork is one of the most widely used vibration-isolating materials. Although the inherent frequency of the vibration-isolating system (hereinafter referred to as the natural frequency of cork) is limited by its application, it is cheap and easy to use And other performance is good, so it is still used for vibration isolation.Cork is usually used for compression.With rubber, cork even if the compression amount of 30% will not protrude laterally.When the load is large, the stiffness decreases, the static stiffness The curve is similar to that of copper. The optimum compressive load of cork is 5-20 t / m 2 (0.5-2 kg / cm -2). The cork damping ratio is about
