Description
Technical Field
The invention relates to the field of brake systems, in particular to a bench brake squeal test method under a humid working condition.
Background
Brake squeal is a vibration problem that is caused by friction between the brake pads and the brake disc. This vibration propagates acoustically, and this problem is called "self-excited vibration". It is different from "forced" vibrations, such as vehicle body vibrations. The self-excited vibration generates further vibration to the self, and the stronger the vibration is, the larger the energy is.
The brake scream is similar to the sound amplification phenomenon, and the principle of the sound amplification phenomenon is as follows: sound enters the microphone from the speaker, is amplified by the loudspeaker, and then repeatedly exits the speaker, eventually becoming louder.
In the case of self-excited vibration, once vibration is generated, it expands and becomes large. The larger the amplitude, the more damping is required to stop the vibration. During braking, the brake pads are in close contact with the brake disc, so it is difficult to attenuate vibration.
In the case of brake squeal, the frequency of generation varies. Even if a brake squeal of a certain frequency is reduced, another brake squeal is generated at a different frequency. Due to different vehicle types, the frequency is different, and besides general vibration, other vibration is difficult to reduce. And the effectiveness of reducing vibration sometimes occurs and sometimes does not.
Brake squeal is caused by friction between the brake pads and the brake disc, so the coefficient of friction of the brake pads correlates to brake squeal. It is therefore quite difficult to both prevent squeal and increase the braking effectiveness, and in practice, squeal occurs when a large amount of energy in the brake pads is transmitted to the brake disc.
The friction coefficient of the brake friction plate is increased due to the oxidation of the surfaces of the brake disc and the brake friction plate, or the moisture absorption of the friction plate is increased, so that the brake squeal phenomenon is easy to occur.
In the existing whole vehicle development project, more and more vehicle types have brake screams under a wet working condition, but the existing bench test method cannot cover the verification under the wet working condition, so that the problem of identification at the bench stage cannot be solved, once the brake screams under the wet environment appear at the whole vehicle stage, the problems are solved in reverse, and the waste of the development period and the development resources can be caused.
