Compared with conventional injection molding, injection-compression molding can mold optical parts with higher precision and lower flow residual stress. However, the melt flow process in a closed cavity becomes more complex because of the moving cavity boundary during compression and the nonlinear problems caused by non-Newtonian polymer melt. In this study, a 3D simulation method was developed for injection-compression molding. In this method, arbitrary Lagrangian-Eulerian was introduced to model the moving-boundary flow problem in the compression stage. The non-Newtonian characteristics and compressibility of the polymer melt were considered. The melt flow and pressure distribution in the cavity were investigated by using the proposed simulation method and compared with those of injection molding. Results reveal that the fountain flow effect becomes significant when the cavity thickness increases during compression. The back flow also plays an important role in the flow pattern and redistribution of cavity pressure. The discrepancy in pressures at different points along the flow path is complicated rather than monotonically decreased in injection molding.

针对工程建设过程中常常通过资源重新配置或提高资源利用率来应对风险事件可能引起工期延迟的问题,提出了基于工期可控性的网络进度计划随机仿真评价方法,以资源配置和利用裕度作为活动的可控性衡量指标,同时考虑了风险事件发生时间不同导致的风险应对措施的可实施性不同的问题,通过对各个风险事件发生时间及其引起的活动持续时间延误、风险应对效果等进行随机仿真,从而对整个项目的工期分布进行模拟,评价编制的网络进度计划的合理性。算例表明:相对于传统的基于工期和基于因素的Monte-Carlo仿真评价方法,基于工期可控性的仿真评价方法得到的结果更为合理。
