摘要: 针对激光加热固化壳体成型过程中材料带表面温度不易控制而影响成型质量的问题,分析了在成型过程中影响材料带表面温度的相关工艺参数并对其关系进行了理论推导。利用经典ANSYS有限元分析软件,建立了热力学瞬态分析模型,模拟了壳体成型过程中材料带表面温度的变化情况,并对仿真结果数据进行了分析。通过实验测试了材料带在工作过程中的温度变化及温度对壳体强度的影响,将实验数据与仿真结果进行了对比,验证了仿真模型的正确性,并且得出了材料带表面成型温度与成型速度及激光功率之间的关系以及成型温度与壳体强度的关系。

Abstract: For the problem that the surface temperature of material tape is so difficult to control in the process of laser heating and solidifying shell forming that influence the molding quality, we analyzed the related technological parameters that affected the surface temperature of the material tape during the forming process and deduced theoretically for their relationship. By the ANSYS finite element analysis software, we built a thermodynamic transient analysis model to simulate the surface temperature change of the material strip during the shell forming and analyzed the simulation results. We tested the temperature changes and the influence of temperature on the strength of the shell through experiments, and then compared the experimental data with the simulation results to verify the correctness of the simulation model, and get the relationship among the forming temperature of the surface of the material, the forming speed and the laser power, based on which the relationship between the molding temperature and the shell strength was deduced.

Key words: laser curing, the surface temperature, finite element analysis, shell strength
