Twin-screw model tetrahedral interstitial volume
≠ volume changes with the size of the schematic,[link widoczny dla zalogowanych], rectangular area, said the volume of the intermeshing region, the area under the curve that the volume of the tetrahedron gap. o Figure 6, () fitted curve of the three 7g () of the fitting curve Fig. 6Three-ordersplinecHl ~ e0I, () F7Splicecu Ⅳ eofg () Clearly, the size of the volume with tetrahedral interstitial ≠ (ie with the z) into a cyclical change, period n / 2. 2 2.1 Closing the model results through engagement with twin-screw extruder to further analysis of the geometry,[link widoczny dla zalogowanych], surface curves obtained at both ends of the intersection,[link widoczny dla zalogowanych], and derive the mathematical model of the tetrahedral interstitial volume, the preparation of the tetrahedral interstitial volume calculation program, enter the diameter of R. Diameter. Lead T, you can calculate the volume of the tetrahedron gap. Table 1 is R = (29 ~ 35) mm, CL = 52mm, T = 56mm for a series of calculated results. The results can be seen from the above: The equation (6) the results calculated v and a simplified cubic spline function (1o) the results of calculated V, is equal in the error range; in cL with constant conditions,[link widoczny dla zalogowanych], surrounded by v the volume of the body and its gap with the meshing body size increased with the ratio of E R, increases, which is consistent with the actual situation. 96 'Beijing University of Chemical Technology 19982.2 conclusions 1) the gap by analyzing the formation of tetrahedral principle, a mathematical model of tetrahedral interstitial volume, the model results with the past weighting results were compared with calculated H can be found, when the R side small or too large, the weighted results are too partial, J, or larger 'This is mainly due to sub == Yan embroidery greater change in the right. 2) accurate calculation of the volume of the tetrahedron gap,[link widoczny dla zalogowanych], for in-depth understanding of tetrahedral-rotating twin screw to provide a reliable basis for the gap. 3) the use of cubic spline function simplifies the calculation of tetrahedral interstitial volume.
