| 目的 针对注塑加工生产的微齿轮运转一段时间后会出现严重变形的问题，对微齿轮注塑精密成形翘曲变形进行分析。方法 基于混沌粒子群建立微齿轮注塑CAE模型，获取曲面全局最优解，在此基础上，计算微齿轮注塑精密成形翘曲收缩率，得到翘曲变形量，同时优化微齿轮注塑精密成形工艺参数，分析微齿轮注塑精密成形翘曲变形情况。结果 将仿真结果与实际试验结果进行对比，得出该分析方法的预测结果与实际翘曲变化趋势完全一致。结论 微齿轮注塑中心位置的翘曲变形量最大，离中心位置越远，翘曲变形量越小。 |

| The work aims to analyze the warpage deformation of micro gear injection precision molding to solve the serious deformation of micro gear produced by injection molding after a period of operation. Based on the chaotic particle swarm, the micro gear injection CAE model was established to obtain the global optimal solution of the surface. On this basis, the warpage shrinkage rate of the micro gear injection precision molding was calculated, and the warpage deformation amount was obtained. At the same time, the process parameters of micro gear injection precision molding was optimized and the warpage deformation of micro gear injection precision molding was analyzed. The simulation results were compared with the actual test results. It was concluded that the predicted results of the analysis method were completely consistent with the actual warpage deformation trend. Through the experiment, it is further concluded that the warpage deformation of the micro gear injection center position is the largest, and the farther from the center position, the smaller the warpage deformation. |
