摘要
针对某车型在颠簸路面行驶过程中车内噪声主观体验较差的问题,结合LMS/TPA模块,建立了路面激励噪声的结构传递路径分析模型,并进行实车道路试验和室内锤击法试验。结果表明:车内目标点的实测噪声与拟合噪声具有良好的一致性,从而验证了TPA模型的正确性。通过对各个路径的贡献量分析,可得出贡献量较大的路径信息,为车内噪声优化提供了依据。
Aiming at the problem of poor subjective experience of interior noise during bumpy road driving, combined with LMS/TPA module, the structural transmission path analysis model of road excitation noise was established, and the real vehicle road test and indoor hammer test were carried out. The results show that the measured noise and the fitting noise of the target point in the vehicle have good consistency, which verifies the correctness of the TPA model. Through the analysis of the contribution of each path, the path information with large contribution can be obtained, which provides a basis for the optimization of interior noise.
