摘　　要：为解决内外犄角曲面喷涂时的犄角处涂层不均匀和涂料浪费问题,基于已有的喷枪模型,提出运用微分几何面积放大定理建立考虑喷枪倾角因素喷涂模型的方法,基于此模型给出了倾角喷涂三种情况下的喷枪轨迹优化目标函数,并运用黄金分割法进行求解,为倾角喷涂模型在喷涂轨迹优化中的应用提供了理论基础。仿真实验表明,喷枪倾角喷涂的建模方法有效;倾角喷涂轨迹优化方法可行,且涂层的均匀度受到喷枪倾角大小和方向的影响。In order to solve the problem of poor coating uniformity and coating waste of inside and outside horns surface in spraying, based on existing spray model, the dip angle spray model was proposed using the theorem of area magnification. The spray tool trajectory optimization functions for dip angle spraying of three cases were proposed according to the dip angle spray model and the golden section method was used to solve it. lt provides a theoretical basis for the application of dip angle spray model in spraying trajectory optimization. Simulation results show that the modeling method of dip angle spraying is effective. The spray tool trajectory optimization method of dip angle spraying is feasible and the coating uniformity is influenced by dip angle and orientation of spray tool.
