汽车顶盖喷涂轨迹的优化

3D Deformation Analysis of Retaining Structures of Foundation Optimization of Spraying Trajectory for the Automotive Roof

在汽车喷涂过程中,涂料经过高速旋杯式静电雾化器到达汽车顶盖时,涂层厚度呈现不均匀的状态。为了更大程度上实现喷涂表面涂层厚度的均匀性,改善汽车喷涂质量,建立汽车表面喷涂轨迹的优化模型,并计算相邻喷涂轨迹间的最优重叠距离。将汽车顶盖离散化为多个三角平面,将汽车顶盖的平面投影按照最佳喷涂间距进行网格划分,求解相应三角平面的节点信息和喷涂该点时雾化器的坐标值,并生成汽车顶盖喷涂轨迹。通过对汽车顶盖喷涂轨迹的计算,为进一步实现对复杂曲面的喷涂轨迹优化提供了理论依据和实践指导。

In the process of automotive spraying,the coating thickness is non-uniform when it reaches the automotive roof through the electrostatic atomizer of the high-speed and rotary.In order to realize the uniformity of coating thickness and improve the quality of automotive spraying,an optimization model of automotive spraying trajectory was established,and the optimal overlap distance between adjacent spraying trajectories was calculated.The automotive roof is discretized into several triangular planes,and the plane projection of the automotive roof is meshed according to the optimal spraying distance.The node information of the corresponding triangular plane and the coordinate value of the atomizer when spraying the triangular plane are solved,and the spraying track of the automotive roof is generated.By calculating the spraying trajectory of the automotive roof,the theoretical basis and practical guidance are provided for further realizing the optimization of spraying trajectory of complex curved surface.
