Method used for laboratory simulation of automobile coating B pillar chromatic aberration

Abstract

The invention discloses a method used for laboratory simulation of automobile coating B pillar chromatic aberration. A device comprises first fixing parts and second fixing parts which are arranged on a base material; a first sheet material is arranged on the first fixing parts, and a second sheet material is arranged on the second fixing parts; the distance between one side edge of the first sheet material and one side edge of the second sheet material is adjusted to be equal to the width of an automobile B pillar; the number of the first fixing parts is adjusted so as to move the first sheet material to be higher than the second sheet material, and the first sheet material and the base material are maintained to be horizontal; and at last, the central axis of the base material is maintained to be overlapped with the central axis of a spraying supporting plate, spraying is carried out, after spraying, the base material, the first sheet material, and the second sheet material are separated from the device, and chromatic aberration and appearance states are observed and measured. The preparation process of the method is simple; the consistency of preparatory work of a plurality of times is convenient to maintain; the method is suitable to be adopted in laboratories; compared with a simulation method in the prior art, the method possesses following advantages: simulation of automobile body coating process can be realized accurately, and experiment result validity and facticity are increased obviously.

Description

technical field [0001] The invention relates to a method for simulating the coating effect of a paint, in particular to a method for simulating the coating of an automobile B-pillar in a laboratory, so as to understand the color difference produced by the color paint during the coating. Background technique [0002] According to the information we have learned, at present, the coating process of major automobile OEMs adopts the method of spraying the outer cavity of the car body and the inner cavity of the car body separately. Due to the needs of internal and external spraying, the parts of the four doors need to be at an opening angle during the paint spraying process (the opening angle is different from each factory, and generally the door opening angle is greater than 45°). After the inner cavity is sprayed, due to the color The paint is in a wet film state and will not be completely closed, so that the front door on the same side and the B-pillar of the body (that is, th...

However, due to the obvious difference from the actual spraying, the spraying effect has always been the difficulty and focus in the experimental process.
