Validation of Moldflow(TM) Simulation with Experimental Data from Mold with Viewing Window.

摘要

In this thesis benchmarking was used to determine the accuracy of the injection molding CAE software Moldflow(TM). The benchmarking data were obtained by experiments; the visualized melt filling behaviors inside rib shape cavities, step-change cavities, and obstacle-pin cavities with tapered thickness using a three-dimensional (3-D) glass-inserted mold. The measured melt temperature distributions along the thickness direction using an integrated thermocouple sensor was developed based on many different molding conditions. The database includes all these important data in addition to material data generally required for numerical simulation.;To determine the accuracy of the simulation software the following three characteristics were compared: fill pattern, injection pressure at three locations, and temperature profile in the runner just before the gate.;The results indicate that the Moldflow(TM) software makes some assumptions that cause the simulation to be not entirely accurate; however the simulation does give a very good understanding of how the mold cavity will fill.
