Numerical model of an electropaint process with applications to the automotive industry. (English) Zbl 0887.65127

The authors consider the problem of electropainting a car. The model for this involves Laplace’s equation with a somewhat complicated set of boundary conditions involving a Signorini problem. They cast the problem into an integral equation involving integration over the boundary and solve it by means of the boundary element method. They formulate a computer model of the throw-power workpiece for the purpose of comparing different paints and discuss the paint distribution on the roofs of cars. Diagrams are given which illustrate this.
