FEM simulation of thermal differences in semi finished glass pieces during the cooling
Havelková, Martina ; Schovánek, Petr
Semi finished glass pieces are moulded in the furnace to template forms not only to fit their shape but also to reduce internal stresses. Thermal differences are unwanted and have to be minimized in the cooling procedure of the glass pieces. Simulations of various types and sizes of shaping forms and complex model cooling were accomplished. The aim of these simulations was to optimise geometric parameters, clamping conditions and material of the form, so that thermal differences at glass are minimized during the cooling.
Numerical modelling of the glass shaping forms cooling
Havelková, Martina ; Schovánek, Petr
The purpose of heat treatment of semi finished glass pieces in shaping forms is not only to fit their shape but also to reduce internal stresses. Thermal differences are unwanted and have to be eliminated in the cooling procedure of the glass pieces. Simulations of different types and sizes of shaping forms and complex model cooling were accomplished. The aim of these simulations was to optimise geometrical parameters, clamping conditions and material of the form, so that thermal differences at glass or glass – form interface are minimized during the cooling.
