摘要：

针对氢燃料商用车燃料电池系统运行噪声问题，本文基于整车NVH测试锁定散热器气动噪声与尾排气动噪声为主要声源。通过集成尾排消音器结构优化、高压风扇气动改性与智能控制策略（含氢阀参数调节及吹扫策略改进）的多维度降噪方案，实现关键噪声源有效抑制。试验表明：驾驶员耳旁噪声在FCV稳态工况下降幅达5 dB（A），关机吹扫阶段降低4.7 dB（A），主客观评价验证优化后声学品质满足工程要求。研究成果构建了“声源识别-多物理场优化-系统控制”的噪声治理体系，为同类车型NVH性能提升提供了可推广的解决方案。

Abstract:

For the operational noise problem in fuel cell systems of hydrogen-powered commercial vehicles， in this study radiator aerodynamic noise and exhaust pneumatic noise are identified as primary sources through vehicle-level NVH testing. By implementing a multidimensional integrated noise reduction solution of exhaust silencer structural optimization， centrifugal fan aerodynamic modification， and intelligent control strategies （including hydrogen valve parameter adjustment and purging strategy enhancement）， effective suppression of key noise sources is achieved. The experimental results show a 5 dB（A） reduction in driver's ear-level noise under FCV steady-state conditions and a 4.7 dB（A） decrease during shutdown purging. Subjective-objective evaluation confirms the optimized acoustic performance meets engineering requirements. The research establishes a systematic noise control framework encompassing "source identification， multi-physics optimization， and system control，" providing a replicable technical paradigm for NVH improvement in commercial fuel cell vehicles.
