中文摘要:
      针对胎架布置过程中耗时耗力,浪费大量物资的问题,提出一种面向船舶分段建造的智能胎架布置坐标快速确定方法。首先,构建船体分段面密度模型,并求解其质心;然后,在胎架轨道和最大支撑载荷的约束条件下,确定胎架最优平面点位坐标;其次,通过拟合船体分段外板的曲面模型,以平面点位坐标及胎架活络头接触角度为条件,确定胎架与外板的接触点;最后,通过坐标换算方法,获取各胎架定位高度,确定胎架布置坐标。 本文选用某典型分段为对象,详细阐述确定胎架布置坐标的确定过程 ,实验结果表明该方法能够减少胎架数量、缩短布置时间。
英文摘要:
      Aiming at the problem of time-consuming, labor-consuming and material-wasting in the placement of frame, this paper presents an intelligent placement method for ship''s segmental construction. Firstly, construct the hull sectional surface density model and solve its center of mass; then, under the constraints of the track of the frame and the maximum support load, solve the optimal point coordinate of the frame ; Secondly, fit the surface equation of the hull sectional outer plate, the contact point between the frame and the outer plate is determined under the conditions of point coordinate and the contact angle of the movable head of the frame; finally, the coordinate conversion method is used to move the frame. The positioning height of each bracket was obtained. In order to verify the effectiveness of this method, a typical section is selected as the object, and the determination process of intelligent placement coordinates of the tire frame under the minimum number is described in detail. The experimental results show the effectiveness of the proposed method.
