The flow guiding device allowance determining method comprises the steps that S1, four flow guiding fin datum points are marked on the outer contour lines of the two ends of a stern steel casting respectively; s2, assigning a bow and stern mounting center line; s3, bow and stern connection points corresponding to the flow guide fins are marked on the bow and stern installation center lines; s4, a connecting contour line is drawn on the stern steel casting; s5, marking a plurality of auxiliary connection points on each connection contour line, and marking corresponding contour marking points on the outer contour line of the inner end of the corresponding flow guide fin in the flow guide device; s6, the stern section is assembled, and the coordinates of the inner vertex of the stern end of the stern steel casting in the stern section and the coordinates of all connecting points of the stern steel casting in the first coordinate system are measured; s7, calculating the coordinates of the two precision control points in the first coordinate system when the flow guide device is theoretically installed; s8, measuring the coordinates of each contour mark point and two precision control points on the flow guide device in the second coordinate system; s9, fitting a coordinate system to obtain a margin; the flow guiding device is convenient to install without allowance.

    本发明的导流装置余量确定方法,包括:S1、在艉部铸钢件两端外轮廓线上各标记4个导流鳍基准点;S2、勘划艏艉安装中心线;S3、在艏艉安装中心线标记出对应导流鳍的艏、艉连接点;S4、在艉部铸钢件上划出连接轮廓线;S5、在每个连接轮廓线上标记出多个辅助连接点,并在导流装置中对应导流鳍的内端外轮廓线上标记出对应的轮廓标记点;S6、组装艉部分段,测量艉部分段中艉部铸钢件艉端内顶点和艉部铸钢件各连接点在第一坐标系的坐标;S7、计算导流装置理论安装时两精度控制点在第一坐标系下的坐标;S8、测量导流装置上各轮廓标记点和两精度控制点在第二坐标系下的坐标;S9、坐标系拟合,获得余量;本发明便于导流装置的无余量安装。
