隔音棉英文
车辆够不够安静,直接关乎到日常行车的舒适性,也影响到品牌在人们心目中的高级感。提到安静,很多人都会想到NVH。NVH是Noise、Vibration、Harshness,即噪声、振动以及声振粗糙度的英文缩写,它的水平高低是衡量汽车品质的重要指标之一,当然也是大家开车时最容易感知到的。关于NVH最典型的一个误区就是,只要舍得下成本塞隔音棉,车辆的NVH表现就一定好。其实不然,要做好一辆车的NVH,首先要从产生噪音和振动的源头入手,其次才是减缓、阻隔噪音与振动的传递,这是一项非常复杂的系统工程。 车子安静与否,先天的底子很重要 别克品牌的车子开起来安静,在广大车主心目中一直都是有口皆碑的。我们以别克旗下搭载别克最高等级静音科技的昂科旗为例,这台车在整车架构开发时就正向输入了NVH的高等级要求。为了打下良好的整车静音基础,首先要做的就是如何主动抑制车身振动,因为它是车辆噪音的源头之一。昂科旗采用的高强度钢的比例达到84%,并且通过车身结构的设计优化,整车拥有极高的扭转刚度,从根子上实现了优异的振动噪声抑制能力。 别看昂科旗块头不小,然而行驶起来风噪并不大,这跟优秀的空气动力学设计密不可分。飞翼式前脸设计优化了车头的迎风面积,智能降阻格栅、空气动力学造型外后视镜、车身底部扰流板、尾部一体式鸭尾扰流板等等一系列空气动力学设计,造就了低风阻系数,不仅可以降低油耗,同时也最大程度的降低了行驶风噪。 发动机也是车辆噪音和振动的主要源头,上汽通用旗下的这台主力Ecotec 2.0T发动机采用了一系列静音技术。包括静音平衡轴系统、下沉式可变排量机油泵、静音平衡链、油轨及声学罩、等面密度玻纤一体式成型发动机罩盖、降噪减振带轮等等,从而达到让发动机运转更稳、噪声更小的效果。另外,不同于市面上很多车型采用的三点式悬置,昂科旗采用四点式悬置,可在保证耐久的前提下,更大程度提升了滤振降噪效果。 可见,一辆车的NVH水平首先取决于先天的底子,如果研发时的底子没打好,比如车身刚性、风阻系数这些一旦开发定型,后续就很难再去做优化改进了。 有了好的底子,还要舍得下料有了良好的静音底子,接下去就是降低或阻隔噪音的传播了。除了大家能看到的在前风挡和前门侧窗部位采用了厚达5毫米的高级声学夹层玻璃,昂科旗的车身填充工艺包含了全车34处膨胀填充材料,以及三道车门密封条,可以说几乎比肩豪华车级的整车气密性了。昂科旗在地板、顶棚、车门、轮罩等区域采用LASD环保轻质止振阻尼,这种液态可喷涂型阻尼隔音材料比传统的隔音垫隔音效果更好、质量更轻,并且还很环保。而在仪表板、手套箱、中央扶手、门板、顶衬和空调控制管道等部位,大量采用高档吸音材料,加之高品质轻质吸声地毯,让噪音进一步降低。后轮罩区域则由2毫米高分子隔音聚合物与高密度泡棉及吸音棉全覆盖,有效隔绝道路噪声。侧翼式前围隔音垫和刹车踏板隔音垫也是同级车型当中比较少见的,双层声学底护板采用轻型热增强塑性复合材料+弹性橡胶材料,从而进一步隔绝发动机和轮胎在车辆行驶时传到车厢内的噪音。 新一代ANC主动降噪系统 说到车载主动降噪,它的基本原理跟飞机头等舱上见到的主动降噪耳机,比如BOSE最有名的QC消噪耳机大致相仿:两个频率和幅值相同的正弦波如果相位正好相差180度,它们叠加后会互相抵消。 昂科旗搭载的新一代ANC主动降噪系统由ANC处理器、扬声器和MIC麦克风三大部分组成,其中最核心的ANC处理器可以根据车辆行驶状况,通过位于顶衬的4个麦克风,持续不断地捕捉发动机传导到车舱内的低频噪音,以专用算法通过扬声器精准释放出与实际噪音相反相位的抵消声波,从而使得车厢内二次谐波噪音水平大幅降低。原理虽不复杂,但是大家也能看出来,这当中ANC处理器的算法和逻辑至关重要。从实际效果来看,BOSE提供的这套ANC解决方案确实不错,除了BOSE自身过硬的技术功底,也得益于BOSE与通用汽车长期的密切合作关系。事实上,包括ANC主动降噪,BOSE专为昂科旗量身定制的Bose Center Point环绕声音响系统的实际感受也是非常棒的。总结 看到这里,相信大家也不难明白,一辆车的NVH水平高不高,不光是要舍得下料,高超的工程研发实力更是至关重要的。让一台车子真正安静下来确实并不是一件简单的事情,绝对不是多塞几块隔音棉能搞定的。 — END —本文来源于汽车之家车家号作者,不代表汽车之家的观点立场。
