摘　　要：以某光伏电站直流检测表壳体为例,利用有限元模拟分析,选取模具温度、熔体温度、保压压力和保压时间为试验参数组合,以翘曲变形量作为成型质量评价指标,建立响应面模型。结合Design Expert软件进行分析,处理数据获得直流检测表壳体工艺成型参数与翘曲变形之间的回归关系。根据方差分析验证二阶响应面模型可以真实有效地反映设计变量与响应变量之间的规律,得到成型直流检测表外壳的最优工艺参数,即模具温度39℃、熔体温度280℃、保压时间15 s和保压压力22 MPa。根据数值分析结果设计注塑模具,实际结果表明该方法可以快速、有效实现注塑模具工艺参数优化。Taking the case of a DC detection meter of a photovoltaic power station as an example, using finite element simulation analysis, response surface model was established by selecting mold temperature, melt temperature, holding pressure and holding time as the test parameter combinations, and using warpage deformation as the evaluation index of molding quality. The data was analyzed and processed with Design Expert software to obtain the regression relationship between the process molding parameters of the DC detection meter and the warpage deformation. The constructed secondorder response surface model was verified by analysis of variance to reflect the law between design variables and response variables in a more real and effective way. The optimal process parameters for the molding of DC detection meter shell were obtained, which was mold temperature was 39 ℃, melt temperature was 280 ℃, holding time was 15 s and holding pressure was 22 MPa. The injection mold was designed according to the numerical analysis results, and the actual results show that the method can optimize the process parameters of injection mold quickly and effectively.
