船舶管系减振材料的应用研究

Application of Damping Materials in Marine Vessel Piping

为适应我国舰船减振降噪的需要，试制出ＱＧＤ－１和ＱＧＤ－２两种穿孔型隔振垫，主要用于管路马脚，也可用于基座等振动部位。对两种隔振垫的阻尼性能、阻燃性能、耐油性能与国外同类产品进行了比较。经管路模型试验和水泵机组试验证明，这两种隔振垫可使管路系统振动加速度级明显下降。

Two types of perforated shims for vibration isolation QGD 1 and QGD 2 are developed for piping clamps and mounts of machines in marine vessel. A comparison is made between the two types of shims and imported equivalents with respect to the damping action, fire retardance and oil resistance. Through piping model test and pump unit trial it is shown that with the two types of isolating shims the vibration acceleration of the piping system can be reduced evidently.
