The invention belongs to the technical field of automobile body systems, and particularly relates to a method for solving whistling of a gap between an automobile engine cover and a grille based on an SNGR method. According to the method, the whistle of the gap between the engine cover and the grille can be accurately analyzed, and the method is not influenced by other wind noises such as rearview mirrors, A columns and chassis; the method does not need to pay attention to the pressure condition of the front windshield or the rearview mirror, and only needs to pay attention to the surface sound power of the whistle attention surface, right facing the front windshield, of the sound source area; according to the method, the risk can be effectively identified in the early stage, the time for finding the risk through real vehicle verification can be shortened, and the development cost problem caused by sample piece manufacturing and test arrangement can also be reduced; the method is very suitable for early development of the whistle between the engine hood and the grille, and is an efficient analysis method.

    本发明属于车身系统技术领域,具体涉及一种基于SNGR方法解决汽车引擎盖与格栅间缝隙口哨声的方法。本发明可以精准分析引擎盖与格栅间缝隙口哨声,不受后视镜,A柱、底盘等其他风噪的影响;本发明不需要关注前档玻璃或后视镜的压力情况,只需要关注声源区正对前档玻璃的口哨声关注面的表面声功率;本发明能够在前期有效识别出风险,既能减少通过实车验证发现风险的时间,也能减少样件制作和试验安排带来的开发成本问题;非常适用于早期引擎盖与格栅间口哨声的开发,是一种高效的分析方法。
