线加热是一种在造船过程中用于生产高弯曲板的方法。在现代化、自动化的造船工艺中，线加热工艺被普遍认为是落后的技术之一。加热过程中的任何信息都不是量化的或计算机化的。这些缺点限制了生产线加热过程的自动化，从而限制了整个造船过程。因此，一种新的基于定量和计算机化加热信息的自动化加热工艺被寻求。本文介绍了一种自动化加热过程的综合算法。通过对完整算法的概述，本文整合了作者单独发表的算法组件。讨论了自动线加热过程的整个过程，包括壳体件建模、壳体开发、曲面板的圆柱逼近、加热信息的计算、测量和表面比较。综合算法可针对不同热源和测量方法进行调整，无需对算法进行根本性改变。所提出的线路加热算法已经实现，并转移到一些造船厂进行定制应用。
Line heating is a method used in the production of highly curved plates in the shipbuilding process. Line-heating process is generally regarded as one of the outdated technologies in the modernized and automated shipbuilding process. No piece of information in the line-heating process is either quantified or computerized. These drawbacks have restricted the automation of line-heating process and, as a result, the entire shipbuilding process. Therefore, a new automated line-heating process based on quantitative and computerized heating information has been sought. This paper describes a comprehensive algorithm for an automated line-heating process. By focusing on the overview of the complete algorithm, this paper integrates the components of the algorithm that have been separately published by the authors. The overall procedure of the automated line-heating process, including shell piece modeling, shell development, cylindrical approximation for curved plates, computation of heating information, and measurement and surface comparison, is discussed. The comprehensive algorithm is adjustable for different heat sources and measuring methods, without incurring fundamental changes in algorithm. The proposed line-heating algorithm has been implemented and transferred to some shipyards for customized applications.
