Background technology
Usually, the longitudinal member that is used to strengthen the longitudinal strength of boats and ships is connected with hull.Yet, owing to partly have fast-changing curved surface with the hull of fore on the quarter, therefore be necessary the longitudinal member that will be on the bow be connected in hull with stern to be carried out the flame forming plate operation corresponding to the curved surface that forms.Below, will the flame forming plate operation be described with reference to figure 1a and 1b.
Fig. 1 is the skeleton view of the longitudinal member of boats and ships, is used to illustrate the bending forming operation of longitudinal member.
Flame forming plate operation with longitudinal member of web (web) Wb and the edge of a wing (flange) F1 comprises lateral thrust operation, vertical curve operation and twist operation.
As shown in Figure 1, when the length direction of longitudinal member is the x direction, Width is the y direction, when being the z direction perpendicular to the direction on x-y plane, the lateral thrust operation is meant at the line L1 that connects F1 upper surface two ends, the edge of a wing with in the central part office of longitudinal member and produces distance W between the upper surface of edge of a wing F1 and the line L3 parallel with the X-axle.
