Abstract
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.
