摘要
在圆锯片激光冲击适张过程中,多个激光光斑搭接扩展形成了较大的冲击区域,进而使圆锯片外缘产生足够的切向拉应力。提出了激光光斑位置的确定原则,并利用MATLAB软件建立激光光斑中心点坐标的计算模型,实现了激光光斑位置的可视化模拟。将计算获得的激光光斑中心点坐标数据提供给工业机械手,即可实现圆锯片的精确适张。
During laser shock tensioning process of circular saw blades,many laser spots overlap and extend to form a large impact region. Thus,sufficient tangential tensile stress is generated at the outer edge of circular saw blades. Determination principle of laser spot position is proposed and a calculation model for the coordinates of the laser spot center is established using MATLAB software,realizing the visual simulation of laser spot position. The coordinates of the laser spot center that are obtained through calculation are provided for industrial manipulators to realize the accurate tensioning of circular saw blades.
