Cycle-Average Simplification

The steady-state cycle-averaged temperature is governed by the Laplace equation  

Here tj- denotes the total cycle time defined as the sum of filling time, packing time, cooling time and mold opening time. The heat flux during the mold opening time is typically very small and may be neglected. 

It is convenient to divide the whole procedure of injection molding simulation into three modules  

The mold cooling analysis and the flow analysis are essentially coupled since the transient cavity wall temperature and heat flux are unknown in both analysis, although in practice one may only need a couple of iterative loops, depending on the required accuracy and efficiency. 

This Chapter will discuss the flow analysis, stractural analysis and the mold cooling analysis in sequence.

The average potentials < yield the MF Hamiltonians of Eq. (38) for the next cycle, until self-consistency is reached. An additional simplification may be obtained by a further separation between the center of mass vibrations of the molecules and their orientational motions ...
