Three-dimensional Finite Element Modeling of Rubber Curing Process

Abstract

This paper describes the development of a finite element model for the simulation of the rubber curing process in a mold. Thermal conductivity and heat capacity of the rubber are assumed to be dependent on temperature. The cure kinetic behavior of the rubber is also assumed to be described by an empirical model proposed by Kamal and Sourour. The governing equation is solved using the finite element method in a three-dimensional Cartesian coordinate system. The applicability of the model is verified by a comparison between the results of the simulation of the vulcanization of a rubber part in the mold with experimentally measured temperature profile. It has been shown that there is very good agreement between the model predictions and the actual data.

Modeling of truck tire curing process by an experimental and numerical method

“…This leads to non-uniform temperature and SOC distributions [10]. To obtain the surface temperature history in tire curing process, the thermocouple method has been used.…”

“…In addition, some researchers studied the curing process by finite element method for other rubber products [10][11][12][13][14][15][16][17]. Ghoreishy et al [10,11] studied the rubber curing process by finite element method, an advanced computer simulation technique for optimization of the thick rubber article curing process [15]. Besides, the finite element method was used to predict the vulcanization-reversion [16] and optimize the curing process of EPDM weatherstrips [17].…”

Experimental and modelling study of superficial elastomer vulcanization by short wave infrared radiation

“…A literature survey showed that several studies about the prediction of vulcanization evolution were performed. A great amount of these studies took an interest to rubber vulcanization in the instance of molding process [4][5][6][7][8] but only few works concerned the vulcanization of extruded profile by radiant technologies [2,9,10].…”

Evaluations of Flow and Mixing Efficiency in the Kneading Disks of a Novel Tri-Screw Extruder

“…With the recent advances in computational fluid dynamics to solve the problems related to rotational fluid mechanics ( ), a large number of studies on the flow and mixing mechanism in the kneading disks of the twin-screw extruders use finite element method (FEM) and finite volume method (FVM) (For example, Alsteens et al,2004;Bravo et al, 2004;Ishikawa et al, 2001;Ghoreishy et al, 2005;Nakayama et al, 2011;Rafei et al, 2009;Sobhani et al, 2010;Yoshinaga et al, 2000;Zhang et al,2009.). In a way, although similar in structure and design to the twin-screw extruder, the tri-screw extruder is different from the twin-screw extruder in the flow and mixing mechanisms.…”
