Numerical simulation on thermal strain characteristics of casting mold for automobile tire

In the present study, aluminum alloy casting mold which consist of eight pieces is introduced as a new technique of tire manufacturing. For the numerical analysis, finite element method (FEM) was used to investigate the thermal strain of casting mold using aluminum alloy during the cooling process. In the concrete, the temperature distributions on the inside of each casting mold, the displacement and stress occurred by temperature variations are investigated to predict the accurate measurement variations of casting mold during the cooling process. In the end, numerical simulation results such as temperature distributions, displacement and stress are presented to help to make the effective and the best mold products. Moreover, the introduced technique of numerical simulation applying a FEM is very useful and important things in the mechanical behavior of materials, especially needs the accuracy improvement such as aluminum alloy casting mold products.
