摘要
针对复杂自由曲面中直纹组合曲面上喷涂机器人喷枪轨迹优化及轨迹连接问题,基于曲面面片造型与智能算法理论,建立了喷枪轨迹优化数学模型,提出一种满足直纹曲面上喷枪轨迹首尾衔接的算法程序。首先,通过曲面特征定义直纹曲面,并对直纹曲面造型处理后建立复合喷涂直纹圆弧面片的喷枪数学模型;其次,选择直纹组合面片交界处的喷枪轨迹为优化对象,依据该模型对直纹曲面及直纹组合面片上的喷枪轨迹进行优化,验证了该模型的有效性;最后,依据轨迹优化模型,设计算法程序并通过仿真实验,验证了该算法程序的可行性与优越性,实现了对直纹组合曲面的连续性喷涂。
To solve the problem of trajectory optimization and connection of painting robot for complex geometry on the free-form sur- faces, based on the combined surface of ruled surfaces, a mathematical model of spray gun trajectory optimization was established, mean- while a kind of algorithm procedure was designed to solve the problem of trajectory connection to spray painting robot on combined sur- face of nded surfaces according to the theory of curved surface modeling and intelligent algorithm. Firstly, according to surface charac- ter, the ruled surface and the paint gun mathematical model for complex geometry on free-form patches was established. Secondly, the se- lected juncture between combined surfaces of ruled surface was optimization by the paint gun model. The effectiveness of above model was verified. Based on the model, a algorithm program was devised. The simulation tests verified the validity and feasibility of the trajectory optimization. The continuity spraying of combined surface of ruled surfaces was realized.
