Abstract

The invention relates to an automotive brake braking MOAN noise analysis solution, which belongs to the technical field of automotive braking, and comprises the following steps: detecting the frequency and decibel value of braking MOAN noise, and judging whether the noise is low-frequency, medium-frequency or high-frequency noise; a plurality of vibration acceleration sensors are installed on a brake support and calipers, and the vibration direction, amplitude and vibration frequency of the brake during braking are obtained; the frequency of the braking MOAN noise is judged and compared with the vibration frequency of the brake part; if the two frequencies are the same, the in-vehicle noise comes from the brake; modeling data obtained by the vibration sensor to obtain an ODS vibration mode, analyzing the ODS vibration mode, and judging which part vibration mode noise comes from or which part which part noise ratio is maximum; the ODS vibration mode is compared with the CAE modal vibration mode, and the rigidity of which part is optimized is determined; the scheme is optimized, a sample piece is manufactured for complete vehicle braking MOAN retest, and whether noise is eliminated or not is determined.

Description

technical field [0001] The invention belongs to the technical field of automobile braking, and relates to a method for analyzing and solving MOAN noise of automobile brake braking. Background technique [0002] Automobile braking noise is one of the important components of automobile NVH. The braking noise reduces the driving comfort of automobiles, which is easy to cause complaints from customers, which may lead to after-sales disputes, disputes and increase of after-sales costs. Quickly and accurately judging and resolving car braking noises will help eliminate customer complaints, improve car braking comfort, and save after-sales costs. Since the braking noise of automobiles is very complex, the mechanism of the noise is also difficult to understand. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the present invention is to provide a solution method for analyzing MOAN noise of automobile brakes. [0004] To achieve the above object, the present inve...
