摘要
通过建立周向倾斜薄壁圆环模型，得到了周向偏移量和倾斜角之间的关系; 通过优选周向偏移角，并基于激光熔覆近净成形技术，获得了结构稳定、高度和宽度误差较小的周向悬臂薄壁圆环。结果表明，满足熔覆要求的熔覆件的偏移角为0.75°，倾斜角为25.95°; 周向倾斜薄壁圆环成形较优的工艺参数组合是周向偏移量为0.11 mm，Z轴提升量为0.224 mm。
Abstract
The relationship between circumferential offset and inclination angle is obtained via the establishment of the model of the circumferential thin-walled cylinder. By the optimization of circumferential offset angle and based on the laser cladding net shaping technique, a circumferential cantilever thin-walled cylinder with stable structure and relatively small errors in height and width is obtained. The results show that the requirements of cladding can be met when the offset angle is 0.75° and the inclination angle is 25.95° of cladding specimens. In addition, the circumferential deviation of 0.11 mm and Z-axis increment of 0.224 mm are the optimal process parameter set.
