Abstract

一种车辆隔音降噪壁板，其特征在于：在机组平台区域车体壁板上粘贴静香阻尼隔声毡。为固定隔声毡，在隔声毡下方使用0.5厚镀锌钢板和自攻螺钉。本实用新型相对于现有技术车辆噪声降低1-3dB(A)。

Description

车辆隔音降噪壁板
技术领域
本实用新型涉及一种车辆隔音降噪壁板。
背景技术
城轨客车的噪声控制一贯受到用户的重视，各车辆制造商都投入了大量的技术力量进行长期研发，在车辆噪声控制方面已有技术多采用减小轮轨噪声，提高车辆的隔声性能；其次是对空调机组进行隔振降噪设计，减小空调系统的噪声，同时改进车辆的结构，消除二次结构振动；全车铺设防寒材玻璃丝棉兼顾吸收部分噪声，但这些隔音降噪方法都不理想。
实用新型内容
本实用新型的目的是提供一种从吸振、隔振、吸音、隔音这4个方面入手来控制整车噪声的壁板，主要是解决空调机组下方的噪声，以免传播到客室内。
为实现上述目的，本实用新型提供一种车辆隔音降噪壁板，其特征在于：在车体壁板上粘贴静香阻尼隔声毡来隔音降噪。
在静香阻尼隔声毡下方通过镀锌钢板和自攻螺钉固定静香阻尼隔声毡。
本实用新型相对于现有技术具有的优点和进步：
机组平台区域车体壁板上粘贴静香阻尼隔声毡后，空调机组下方较以往车辆噪声降低1-3dB(A)。
附图说明
附图是本实用新型的结构示意图。
具体实施方式
参照附图，车体壁板4上粘贴静香阻尼隔声毡1，为固定静香阻尼隔声毡，在其下方使用0.5厚镀锌钢板2和自攻螺钉3。

Claims (2)

1.一种车辆隔音降噪壁板，其特征在于：在车体壁板上粘贴静香阻尼隔声毡。
2.根据权利要求1所述的车辆隔音降噪壁板，其特征在于：在静香阻尼隔声毡下方通过镀锌钢板和自攻螺钉固定静香阻尼隔声毡。
