1. **数字孪生定义与需求**:数字孪生是高保真虚拟模型,需整合几何、材料、工艺条件,用于优化注塑过程(填充、保压、冷却、变形预测)。 2. **翘曲预测关键要素**:需精确的压力-热历史,依赖模型定义(设计、流道、冷却)、工艺参数(温度、压力)及材料数据(黏度、热性能、收缩率)。 3. **STAMP技术优势**:STAMP(收缩调整机械性能模型)是CRIMS的升级版,通过压缩因子补偿黏弹性和取向效应,尤其适用于3D复杂模型,提升翘曲预测准确性。 4. **案例验证**:对4种材料(TPV、PE、PP+FRM、PP+GF)的测试显示,STAMP显著改善PE材料的收缩预测(流动方向+88%,横向+36%)和平面度(+73%),但对低收缩材料(如PP+GF)提升有限。 5. **核心结论**:准确模拟需正确输入(模型、工艺、材料数据),STAMP对高收缩材料效果显著,但需结合具体应用场景。
