摘要

传统的气体火焰加热在船体板成型过程中存在加热效率低、可重复性差的缺点。然而，高频感应加热在上述方面显示出其独特的优势。建立了复杂弯曲船体板高频感应加热的数值模型。通过与前人研究的温度响应和结构随时间的响应对比，验证了该方法的可行性。对模型的约束方法进行了改进。通过设置6个单向支架，可以准确模拟船厂的实际成形条件。该模型能准确地计算出挠度。在仿真所需船体板的成形参数和几何参数正确的情况下，该模型可以准确地分析参数对挠度和收缩的影响。为船体板高频感应加热自动化技术提供理论和数据支持。为航空航天、汽车工程、建筑等领域的曲面板成形提供参考。

Numerical calculation of high frequency induction heating for complex hull plate considering deflection

The traditional gas flame heating in the hull plate forming process has the disadvantages of low heating efficiency, poor repeatability. However, high frequency induction heating shows its unique advantages in the above aspects. The numerical model of high frequency induction heating for complex curved hull plate is established. Its feasibility is verified by comparing with the temperature and structural response over time in the previous research. The constraint method of the model is improved. By setting up six one-way supports, the actual forming conditions in shipyard can be simulated accurately. The model can accurately calculate the deflection. Under the correctly forming and geometric parameters of the hull plate required for simulation, the model can accurately analyze the influence of the parameters on deflection and shrinkage. Theoretical and data support are provided for hull plate high frequency induction heating automation technology. It also can provide reference for the forming of curved plates in the fields of aerospace, automobile engineering and construction.

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
