| 摘 要： | 为有效解决船用中厚钢板复杂曲面加工问题,研究空气冷却(空冷)、正面水冷和反面水冷方式对大尺寸钢板弯曲成形的影响因素。首先采用COMSOL Multiphysics仿真平台模拟电磁感应加热和冷却变形多物理场同步耦合过程,然后分析各种因素对大尺寸钢板弯曲成形的影响,最后通过试验验证有限元模型的可靠性,并对感应加热弯曲成形效果进行评估。结果表明:相对于水冷,空气冷却对钢板Y向位移改变效果显著;相对于空气冷却,水冷对钢板角位移的改变影响明显;当频率为50 k Hz时,电流频率对表面温度和角位移影响显著;当钢板长宽比不小于1∶2时,Y向位移的增加比较显著;当长宽比约为1∶1时,角位移的改变比较明显。
