摘要
针对圆锥面的涂层厚度均匀性优化问题,基于一种抛物线的静态喷涂模型,提出基于圆截线的等间距喷涂路径生成方法,并建立喷枪沿圆弧路径动态喷涂的涂层厚度分布模型,以两相邻喷涂轨迹间涂层厚度方差最小为优化目标函数,对喷涂轨迹上的喷涂速率和喷涂高度进行了优化。最后在Robotstudio软件中对机器人喷涂进行仿真,并对喷涂后的涂层厚度均匀性进行数值模拟,结果表明本文提出方法的有效性和可行性,且同时优化喷涂速率和喷涂高度获得涂层厚度均匀性比单独优化喷涂速率的要好。
Aiming at the optimization of coating thickness uniformity of conical surface,based on a parabola static spraying model,a method of equal distance spraying path based on the circle section is proposed,and a coating thickness distribution model of dynamic spraying along the arc path of spray gun is established.Taking the minimum variance of coating thickness between two adjacent spraying tracks as the optimization objective function,the spraying rate and the spraying height on the spraying track are optimized.Finally,the robot spraying is simulated in the Robotstudio software,and the uniformity of coating thickness after spraying is simulated.The results show that the proposed method is effective and feasible,and the uniformity of coating thickness obtained by optimizing spraying rate and spraying height is better than that obtained by single optimizing spraying rate.
