摘　　要：从某一实际工程应用背景出发,在20Hz^400Hz范围内,采用相同的实验方法研究了0Cr18Ni9Ti不锈钢与Fe-16Cr-2.5Mo合金圆筒状构件在宽频带激励条件下的减振降噪性能。结果表明,在20Hz^400Hz频带内Fe-16Cr-2.5Mo阻尼合金使振动得到有效抑制,降噪效果也很明显。Based on the background of some engineering applications, the damping effects of the cylindrical components made in Fe-16Cr-2.5Mo alloy and 0Cr18Ni9Ti stainless steel were studied by using transfer function method in 20-400 Hz frequency range under the identical experiment conditions. The results indicate that, Fe-16Cr-2.5Mo damping alloy can control the vibration effectively, and noise can be reduced evidently.
