摘　　要：马鞍形是船体外板中比较常见的一种,在船体板的冷压成形中回弹是影响成形质量的主要因素之一。针对马鞍形船体钢板冷压及回弹过程进行仿真模拟,并着重探讨了板厚及曲率对回弹特性的影响规律,为工程实践中如何把握回弹规律开展模具补偿设计提供参考依据。The saddle-shaped hull plate is common for ship hull plate. Springback is one of the main problems influencing the forming quality of ship hull plate in air-bending. The simulation is carried out on the air-bending of the saddle-shaped ship hull plate and the springbaek process. The rule of the influence of the sheet thickness and the curvature on the springback characteristics is discussed. It provides a reference for the compensation design of the mould according to the springback rule in the engineering practice.
