摘　　要：采用冲压成型和焊接/胶接工艺制备两种多孔型橡胶填充金属波纹板,并对这类金属波纹板的隔声和减振性能进行研究。通过隔声实验对比金属波纹板和填充了多孔型橡胶的金属波纹板的隔声性能,并通过冲击实验,对比金属波纹板和填充多孔型橡胶金属波纹板的自由衰减过程。实验结果表明:金属波纹填充多孔型橡胶板后隔声能力和减振性能均得到显著提升。Two metallic corrugated sandwich panels filled with porous rubbers are fabricated with stamping forming technique and welding/adhesively bonding technique respectively.The acoustic insulation and vibration damping properties of the metallic corrugated sandwich panels are investigated experimentally and compared with those of sandwich panels filled with porous rubbers.The results demonstrate that the acoustic insulation and vibration damping properties of the metallic corrugated panels are greatly improved by filling porous rubbers.
