摘要/Abstract

摘要： 采用声压法与声强法分别测量地板隔声量,整个频段内测量结果有较好的一致性,且差值在合理的工程误差范围内,规避了试验失误,为后续仿真方法验证提供了一定的保障,而且静音地板的隔声性能优于普通地板。通过脉冲衰减法测量阻尼损耗因子以用于FE-SEA混合法计算隔声量,计算结果与试验结果吻合良好。表明使用FE-SEA法预测静音地板的隔声性能行之有效。分别调整静音地板中胶合板和橡胶层的厚度以期获得隔声性能更优的结构,当橡胶层厚度均为2 mm,胶合板三层厚度分别为3 mm、5 mm、7 mm时,隔声效果更佳。从结构改进到声学包装等主动和被动两个方向优化静音地板隔声性能,建立用户数据库。

Abstract: Sound pressure and sound intensity methods were used to measure the Transmission Loss (TL) of silent floor of high-speed train. Results of the two methods are in good agreement that the difference is within a reasonable range of engineering error, which avoid experiment muff. The results also provide certain reliability for subsequent simulation verification. It is shown that the sound insulation effect of silent floor is better than that of general floor. The damping loss factor was measured by pulse attenuation method, which was then used to calculate the TL using FE-SEA hybrid method. The calculation results of TL are in good agreement with the experiment results. Better sound insulation structure can be obtained by adjusting the thickness of plywood and the rubber layer. It is shown that when the thickness of the rubber layer is 2 mm and three layers of plywood have different thickness of 3 mm, 5 mm and 7 mm respectively, the silent floor has better sound insulation performance. The sound insulation performance of the silent floor can be optimized by improving the floor structure and the sound package, to establish the users' database.
