| 中文摘要: |
| 采用Moldflow对注塑件的熔接痕进行CAE模拟，将Moldflow模拟注射成形后的结果数据导入到Algor中对制件做特征值屈曲分析，并将屈曲载荷因子作为注塑件熔接痕性能的评价指标。通过正交试验，分析了熔体温度、模具温度、保压压力、保压时间对制件屈曲载荷因子的影响。结果表明：熔体温度对熔接痕力学性能影响最为显著，保压时间和模具温度次之，保压压力影响最小。 |
| 英文摘要: |
| Weld line defects were simulated by the technology of Moldflow simulation analysis, then the results of Moldflow were put into the Algor software to make eigenvalue buckling analysis via the CAE interface. Buckling load factor was used as evaluation index of weld line property. The effects of process parameters about melt temperature, mold temperature, packing pressure, packing time on degree of buckling load factor can be found via orthogonal experiment. Finally, the results indicate that the melt temperature has the biggest influence on buckling load factor, followed by the packing time and mold temperature, but the packing pressure has the smallest effect. |
