Abstract

The invention relates to a prediction method for an influence of an interior part on vehicle sound insulation and sound quality. The prediction method comprises the following steps: step 1, adjustingthe working condition of the vehicle; step 2, arranging a sensor; step 3, collecting noise in the vehicle under various working conditions; step 4, checking the consistency of data; step 5, processingand analyzing the noise data; step 6, obtaining virtual "digital interior part"; and step 7, predicting the noise level of the tested vehicle. According to the prediction method for influence of interior part on vehicle sound insulation and sound quality, the final sound insulation level of the complete prototype in the early stage of vehicle development can be predicted, the research and development costs can be reduced, and the development efficiency of the vehicle can be improved.

Description

technical field [0001] The invention relates to automobile performance testing, in particular to a method for predicting the influence of interior trim parts on sound insulation and absorption and sound quality of a complete vehicle. Background technique [0002] At present, the noise of automobiles has become one of the important indicators of customers' overall impression and evaluation of automobiles. How to reduce automobile noise and improve sound quality is an important topic in the development of automobile technology today, and has received extensive attention from various vehicle manufacturers. [0003] In the process of automobile development, it is necessary to conduct vehicle-level noise tests on tooling prototypes many times to evaluate the noise level of the vehicle, analyze related problems, and formulate optimization plans. [0004] Due to the late determination of the shape of the interior parts, the prototype car in the early stage of development does not h...
