Simulative study on electrophoretic coating thickness of battery enclosure of new energy car
[Introduction]It is a new application for the battery enclosure of new energy car to undergo pretreatment and electrophoretic painting process with the car body in white in a paint shop of automotive manufacturer.[Method]The structure of a battery enclosure and its hanging way on the conveyor in an electrophoresis line were described.The electrophoretic coating thickness of the parts was assessed by simulation.The effects of anode arrangement,voltage,the spacing between two parts,and the amount of parts on coating thickness distribution were studied.The simulation result was compared with the on-site validation result.[Result]As many as 12 battery enclosure parts could be placed on a rack with an inter-part spacing of 300 mm.[Conclusion]The battery enclosure parts and car body in white can undergo electrophoretic painting process on the same line.The simulation results suggest a reasonable operation proposal.
