| 摘 要： | 针对船体球扁钢肋骨三角形加热矫正纵向弯曲变形时加热区的计算,通过全站仪测量肋骨与板材线型,使用非均匀B样条拟合曲线后计算了两者的装配偏差。研究了矫正时加热区的计算算法和计算流程,在MATLAB的GUI模块中开发了球扁钢肋骨三角形加热区预报系统,实现了肋骨与板材线型测量数据的导入、曲线的拟合、装配偏差的计算、三角形加热的位置与工艺参数的准确预报。研究内容和成果对火工矫正球扁钢肋骨纵向弯曲变形的现场施工提供了一定的参考和指导。

| Abstract: | As to calculating the heating-area when triangle-heating is used for correcting the longitudinal bending deformation of ship flat bulb steel frame, the paper uses Total Station to measure the line of frame and plate, calculates the assembly deviation after fitting the lines by general non-uniform B-spline. And explore the calculation algorithm and process of calculating the heating-area, then develop the flat bulb steel frame triangle heating area forecasting system in GUI of MATLAB, realizing the function of import of linear measurement data, line fitting, calculation of assembly deviation, prediction of heating-area and technological parameter. The content and achievement can provide a certain reference and guidance for site operation of frame correcting. |
