制动噪声试验方法及模糊评价

Testing Methods and Fuzzy Evaluation of Braking Noise

本文在大量道路试验的基础上，针对制动噪声随机性大和重复性差的特点，提出了一套关于制动噪声测试的试验方法和评价方法。该评价方法应用了模糊数学的原理，对制动噪声进行模糊综合评价，最终给出汽车的总评分和评语，具有明显的分辨率。这种模糊综合评价方法也同样适用于汽车其它性能的综合评价和汽车的总评分。

In the light of the inevitable randomness and worse repeatability in braking noise measurement, a set of testing and evaluating methods for braking noise measurement is proposed based on a large amount of motor vehicle road tests. The principle of fuzzy mathematics is utilized in the evaluating method, therefrom the braking noise is comprehensively evaluated by fuzziness, finally the evaluating mark and comments, which have evident distinguishability, to the motor vehicle are given. This fuzzy comprehensive evaluating method can also be suitable for comprehensively evaluating other Performance of motor vehicles and giving them a general mark.
