Analysis and optimization for E-coating Holes of an SUV 2019-01-0802
In view of the problem of substandard film thickness frequently occurring in the A pillar, In this paper, ECoatMaster was used to conduct electrophoresis simulation analysis on A pillar of an SUV, By calculating the distribution of macro film thickness of the car body, the results of the section of A pillar were intercepted and imported into the micro module to explore the relationship between the opening radius and the thickness of the electrophoretic coating and the influence range of the coating. found that when the pore diameter gradually changes from R6 to R10, film thickness increase significantly, the basic linear increase; When the pore diameter gradually changes from R10 to R14, the film thickness increases correspondingly, but the film thickness increases gradually. At the same time, in order to investigate the relationship between different pore diameters and the influence range of coating film, the influence range of five different pore diameters was compared. Similarly, when the pore diameter was gradually changed from R6 to R10, the influence range was significantly increased, with a maximum increase of 5.1mm. When the pore diameter was gradually changed from R10 to R14, the range of influence increases gradually. the range of influence also tends to be flat, with a maximum increase of 1.7mm. Through comprehensive comparison, it is found that R10 is the best for improving the flow performance of the liquid and improving the thickness of the electrophoretic coating. This research is of guiding significance for promoting the development of high-performance vehicle and improving the electrophoretic process.
