Optimal Cure Steps for Product Quality in a Tire Curing Process

摘要

Numerical algorithms and computer programs have been developed to determine optimal cure steps in a tire curing process.A dynamic constrained optimization problem was formulated with the following ingredienst:(10 and objective function that measures product quality in terms of final state of cure and temperature history at selected points in a tire;(2) constraints that consist of a process model and temperature limits imposed on cure media;(3) B-splines representation of a time-varying profile of cure media temperature.The optimization problem was solved using the complex algorithm along wiht a finite element model solver.Numerical simulations were carried out to demonstrate the procedure of determining optimal cure steps for a truck/bus radial tire.
