摘要
激光弯曲是一种利用激光加热来实现构件的柔性成形技术。通过量纲分析建立了板料激光弯曲过程中弯曲角度的仿真模型,根据试验数据对模型的相应参数进行回归求解,获得了该过程的控制模型。研究结果表明,利用量纲分析法仿真复杂的激光弯曲过程是简便有效的,基于仿真模型无因交次群组合的设计相应的参数可使控制模型达到较高的预测精度。
Laser bending of sheet metals is a highly flexible forming technique.Simulation model of laser bending process has been established by dimension analysis with the control model of laser bending achieved based on regression of laboratory simulate data. It was shown that the dimension analysis was an effective method in simulating the complex laser bending process, and the control model that came from non-dimensional group data of simulations, was a high-accuracy model in predictive analysis.
