Research on the S&R Evaluation Method of Automobile Seats Based on the BSR Tests
摘要
Abstract
In order to determine whether the specific parts have BSR phenomena, a squeak and rattle shaker system is employed for the subjective evaluation of the BSR tests. Since subjective evaluation has the disadvantage that it depends greatly on evaluator's experiences and is less identical, some other efficient and accurate methods for S&R evaluation need to be developed. In this paper, the collection and processing methods of the load spectra in the seat S&R test are described in detail. Then, the method of S&R evaluation of the seat noise is discussed. Through the regressive analysis of the subjective evaluation results and the acoustic parameters data, the objective acoustic parameters which can reflect the subjective evaluation results are summarized. The method is practical in engineering and can effectively identify the BSR.关键词
