To address the issue of low simulation accuracy, and large test resources investment in the development of acoustic package, this paper proposed a method based on ray tracing to calculate the external sound load of car body. Firstly, the hard wall panel on external surface of vehicle was extracted, and ray tracing solving model was established in VAOne. Secondly, the noise value of the key sound source of the vehicle was tested. Finally, the key noise sources were loaded into the ray tracing model to calculate the external acoustic load of the car body. With an SUV as the research object, the vehicle exterior acoustic load was calculated and compared with the test results. The result shows that the sound load calculated by the ray tracing model is in good agreement with the experimental value, which can improve the simulation accuracy of the acoustic package development.

为解决用整车统计能量模型进行声学包开发时仿真精度低、试验投入大的问题,提出了一种基于声线跟踪法计算车体表面声载荷的方法。首先,提取车体外表面硬壁板,在VAOne软件中建立声线跟踪法求解模型;其次,测试得到车体关键声源的噪声值;最后,将关键噪声源加载到声线跟踪法求解模型计算得到车体表面声载荷。以某SUV车型为研究对象,进行车体表面声载荷计算,并与试验测试结果进行对比,结果表明:应用声线跟踪法计算得到的车体表面声载荷与试验值一致性较好,可提高声学包开发的仿真精度。
