量产车型噪声主动控制系统性能实测与分析

摘要
车内噪声控制是汽车NVH (noise, vibration and harshness)研究的重要内容之一。传统的被动控制技术对中高频(≥500 Hz)噪声非常有效,但对低频噪声效果不明显。主动噪声控制(active noise control, ANC)基于相消干涉原理,非常适合控制低频噪声,已被众多车型全系标配。目前,学术界关于主动噪声控制的研究主要集中在新型控制算法的开发和性能优化上,而工业界对于主动噪声控制效果的报道比较片面,公开、全面的实测结果较少。为给学术研究提供参考,同时让更多主机厂了解主动噪声控制系统的实际效果,以某全系标配发动机噪声主动控制系统的量产车型为研究对象,分别在定置和行驶工况下对其主动噪声控制系统的性能和系统鲁棒性进行了全面的测试。测试结果表明:该系统较好地控制了发动机噪声且鲁棒性良好。
Vehicle interior noise control is one of the most important research areas in vehicle noise, vibration and harshness(NVH). Conventional passive noise control technology is very effective for medium and high frequency noise(higher than 500 Hz), but ineffective for low frequency noise. Active noise control(ANC), base on destructive interference, is suitable for controlling low frequency noise and has been adopted as standard configuration by the whole series of many mass production vehicle models. So far researchers in academia concentrate on developing new algorithms and optimizing their performance mainly while the report on the effect of active noise control in industry is one-sided and there is little detailed measurement results published on ANC system installed in mass production vehicle. In order to provide reference for academic research and more detailed information about the actual effect of active noise control system to car makers, the performance and robustness of the ANC system installed in a commercial vehicle are tested when the car is stationary and running, respectively. Experiment results show that the ANC system has good control of the engine noise and good robustness.
