中文摘要:
为提升其隔声性能,通过有限元法数值分析,比较了不同位置墙板的连接方式对房间隔声性能的影响。结果表明：(1)侧墙墙板柔性连接处理对侧向传声的抑制作用显著,当侧墙墙板采用柔性连接后,房间的隔声量在低频段平均可以提升3 dB左右；(2)公共隔墙墙板的柔性连接对房间低频段隔声量提升不明显,甚至在160 Hz、400 Hz、500 Hz等频率下隔声量有所降低。最后,基于模拟分析结果对装配式墙体连接方式提出了改进策略。
英文摘要:
In order to improve the sound insulation performance of steel-structured prefabricated dwellings, a finite element method numerical analysis was used under different conditions. Simulation results showed that the junction modes of wall panel had influence on the sound insulation performance of two adjacent rooms: 1) The flexible junction of side wall panel had obvious effects on inhibiting sound flanking transmission, and the sound insulation capacity was improved by nearly 3 dB in low frequency; 2) The flexible junction of the partition wall panel had no obvious effects. The sound insulation was not significantly improved in low frequency, and it indeed decreased at 160 Hz, 400 Hz, 500 Hz. Finally, based on the simulation results, the improving strategies were proposed for the wall panel junction construction of steel-structured prefabricated dwellings.
