Abstract
Aimming at path optimization of a spray painting robot for big curvature similar natural quadric surfaces, based on the spray gun 3D model of natural quadric surfaces, and spray requirments, the big curvature similar natural quadric surface was fitted into the combination of natural quadric surfaces. Using the methods of adjusting the spray radius and trajectory partition the calculation method of coating thickness and optimization of parameters was discussed for natural quadric surfaces. Taking a car rear bumper as an example, the trajectory optimization was carried out at the junctions of cylndrical surface, conical surface and plane. Simulation results show that the spray gun 3D model can improve the coating uniformity of surfaces;optimized parameters of limited points are fitted on surfaces, the spray velocity indicates non-linear variations with spacing distance and other parameters follow linear variations on the conical surface and spherical surface; the optimization method is feasible on the junctions of the different patches.关键词
