摘　　要：本文介绍一种用于受力构件的减振降阻尼材料——不对称型复合阻尼钢板。它的平面板结构的损耗因子在10^(-2)量级。模型试验中,白噪声激励下的总振级下降5.8～12分贝,平均为9.4分贝。This paper introduces a sort of damping material reducing vibration noise used for components suffered forces i.e. composite damping steel plate with asymmetrical structure. The loss factor of its flat plate structure in on the order of 10-2. In model test, total vibration levels under exciting of white noise is lowered 5.8 - 12 dB, the average value is 9.4 dB.
