Vulcanization Control Method and Vulcanization Control System

摘要

A vulcanization control method and a vulcanization control system are provided that are capable of preventing insufficient vulcanization while shortening a vulcanization time and obtaining an optimal vulcanization time instantly, even when a simple analysis model is used. Data (Xi) of predetermined types of vulcanization-affecting factors (X) are input into a computation device (2) by an input device (6) before vulcanizing a green tire (G). Using the input data (Xi), a change in temperature distribution of a tire cross section over time is calculated with a one-dimensional thermal conduction model for a tire cross-section that passes through a vulcanization rate-limiting section. On the basis of the calculation results, a vulcanization time Tc is instantly calculated. Upon calculating the vulcanization time Tc, a safety time Ts set on the basis of each vulcanization-effecting factor (X) is shortened on the basis of the input data (Xi) of the individual vulcanization-affecting factors (X).
