| 摘 要： | 采用MSC.Marc非线性有限元软件,对板料激光弯曲过程进行了数值模拟.试验与数值模拟的相互印证表明:数值模拟的模型正确,计算过程可靠,计算结果可为板料激光弯曲工艺参数的选择提供依据.通过模拟多道次直线照射的过程可知,变形效果受照射路径次序的影响很大,应选择从固定端向自由端方向交替的双向照射路径,以保证板料在宽度方向上变形的均匀.模拟结果可为带筋结构壁板激光弯曲成形提供实用方案. |

| Abstract: | Laser bending process was numerically simulated by the FEM software of MSC.Marc.The experiment results were compared with the simulation ones,and the temperature and displacement curves of experiment and calculation were in good accordance.The comparison indicates that,calculated model is regarded as correct and the calculated process is considered to be credible,and calculated result will lay foundation for chosen laser parameters.More irradiation paths influence on displacement effect was discussed by num... |
