【正文】 draw every one of the frames in the lines drawing. Later, a fullscale version of the template is used in lofting the lines drawing and in creating the physical frames themselves. It introduces consistency and goodness checks into the creation of original designs, funneling the designer39。s creativity into the production of a new boat of original design in a relatively short time, a new boat that is hydrodynamically smooth as a consequence of the interrelations imposed between and among the templatebased frames. 本專利提出基于單框 架曲面板船體設(shè)計(jì)和建造方法。 [18]Masuda Seiji,Kasahara Shape Decision Method[P]. JP2020347984, 20200608. To easily decide an optimum hull shape in a short time. This hull shape decision method has a step for calculating a Cp curve of the hull shape from one hull shape satisfying inputted design conditions of the hull shape, expanding the calculated Cp curve to a B spline function, changing a control point of the B spline function to change the Cp curve, changing the hull shape from the changed Cp curve, and finding a viscous resistance of the hull shape from the changed hull shape. The hull shape calculated from the Cp curve of the control point corresponding to a minimum viscous resistance in the case that the control point is sequentially changed within the design conditions is decided as the optimum hull shape under the design conditions. 本專利提出一個(gè)船體形狀 決定 方法。從一個(gè)滿足輸入的船體形狀設(shè)計(jì)條件的船體形狀的 CP曲線,擴(kuò)大計(jì)算 CP B 樣條 函數(shù)曲線,改變控制點(diǎn)的 B 樣條函數(shù)從而改變 CP 的曲線,從更改后的 CP 曲線改變船體形狀,并尋找一個(gè)改變船體形狀的粘滯阻力。 [19]Koser Jaroslav DIPLING,Eder Theodor DIPLING. Method and device for determining the bending curve for stretch bending the outside profile elements of a ship39。s hull[P].EP86890192A,198734. The present invention relates to a template, which can be adjusted by means of screw clamps and consists of profile elements (2) which are connected by means of straps (4), for determining the bending curves for outside profiles (3) of a ship39。s side, the profile elements consisting of sections (2) of the profile (3) of the ship39。s side which are connected to one another by means of screws (5) and straps (4), but in the case of nonuniform flanges the thicker flange part (8) is recessed, . is reduced to the width of the thinner flange, at those points where the profile bears against the bulkheads. 本發(fā)明涉及到一個(gè)模板,它可以通過螺絲鉗調(diào)整和 配置,包含以下元素:( 2)連接肩帶( 4), 13 確定船邊曲線外型材的彎曲度( 3)。 [20]Igarashi Kazuyoshi,Igarashi tapered batten[P].JP61000424, 198616. To obtain a sail of good controllability, by uniformly laminating a rectangular batten by molding to be cut and forming a circular arcshaped slope in the point end of the batten. A rectangular batten 4 is uniformly laminated by molding, and the batten 4, cutting a part of its point end 6, forms a circular arcshaped slope 5. As the result, the point end part forms a strong curved surface in one side while a gentle curved surface in the opposite side. Consequently, a sail of good controllability is obtained by deenergizing wind force when a ship returns to the land. 一個(gè)長方形板條 4 均勻成型夾層,板條 4,切割點(diǎn) 6 末的一部分,形成一個(gè)圓弧形的坡度 5。結(jié)果,終點(diǎn)部分在一側(cè)形成一個(gè)強(qiáng)曲面,對(duì) 面形成一個(gè)弱曲面。 [21]Western William J T. Moulding apparatus[P].US4179093A,19780901. Moulding apparatus for moulding an opentop bowllike shell, such as a boat hull, prising: (a) a flexible form layer adapted to form a moulding face for the shell, (b) template means defining an edge around a curved part of the shell, and (c) containment means adapted to form together with the form layer a fluid tight container, the arrangement being characterized by the provision within the container of further template means corresponding in shape to a contour or surface portion of the curved part of the shell, the form layer being drawn down to overlie and be supported by the further template means when the container is evacuated. 成型器具成型一個(gè)開頂碗般的外殼,如船體,包括:(一)適應(yīng)外殼一次成型,(二)模 板定義周圍的彎曲部分的殼,(三)形成與形成層流體密封的容器中。
