摘要
针对表面有凹凸结构的复杂曲面,采用匀速喷涂方法,曲面上曲率的变化造成涂层厚度差较大.根据实验数据推导出平面上的漆膜累积速率二次函数后,采用微分几何的面积放大定理推导出自由曲面上的漆膜累积速率二次函数.为提高曲面上涂层厚度的一致性,采用轨迹优化方法对表面有凹凸结构的复杂曲面的涂层厚度差进行补偿.最后通过计算机仿真验证了数学模型和优化算法的有效性和可行性.
The changes of curvature in concavo-convex surface resulted in great non-uniform paint deposition when speed was constant. After the quadratic function of coat deposition rate for plane was provided according to the experiment data, one for arbitrary curved surface was studied by using the area magnification concept with differential geometry. Trajectory optimization method was applied to compensate coat thickness difference of complex curved surface with concavo-convex structure to improve the uniformity of coat thickness. Simulation results prove that the model and optimization algorithm are feasible.
