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;其次,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;再次,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。文章选用某典型分段为研究对象,详细阐述确定胎架布置坐标的确定过程,试验结果表明该方法能够减少胎架数量,缩短布置时间。Aiming at the problem of time-consuming, labor-consuming and material-wasting in the bracket layout, the paper presents an intelligent bracket layout rapid determining method facing to ship segmental construction. Firstly, the hull sectional surface density model is constructed and its center of mass is solved. Then, under the constraints of the track of the bracket and the maximum support load, the optimal point coordinate of the bracket is determined. Thirdly, by fitting the surface equation of the hull sectional outer plate, the contact point between the bracket and the outer plate is determined under the conditions of point coordinate and the contact angle of the movable head of the bracket. Finally, through the coordinate conversion method, the positioning height of each bracket is obtained and the bracket layout coordinates are gained. A typical section is selected as the research object, the determination process of the bracket layout coordinates is described in detail. The experimental results show that the method can reduce the bracket quantity and shorten the layout time.
