Research On Finite Element Analysis And Optimization Design Of Tire Curing Press Force Components Based On ANSYS

The tire molding curing presses are key equipment of tire manufacturers. The framework is a primary mechanism in the tire molding curing press, witch structural design is reasonable or not directly affects the curing performance and reliability. The beam and base are the most important suffering force part of it; witch deformation has an important influence on the quality of the tire. The structure and force of the beam and the base is complex and suffer a larger pressure at the actual tire curing vulcanization job. The analysis of their stress and strain distribution is highly practical significance for the design of the components and to improve its reliability and service life.The current paper analyzed the key parts such as beams and bases in the framework using finite element method (FEM) according to the requirements of certain molding curing press factory of Shan Dong province. It adopts the finite element method ANSYS software to establish the major component upper beams and bases part of 170" open pan works stereotypes tyre molding curing press model, and to carry on a stress and strain analysis. Throughout analysis, the stress and displacement distributions were obtained and the security was verified.The stress analysis of the beams and the base in the past was not taken into consideration the effects of temperature. The author goes into the research deeply, based on the practice of the tyre press, through the use of finite element analysis software ANSYS, carried on a coupled thermo-mechanical analysis on the beams and the base, and made a comparison with the mechanical analysis. By analyzing, we could observe the stress distribution of the basic agreement, but there were changes in size. This showed that in the tire curing process, the thermal stress generated by temperature was not neglected. The traditional mechanical analysis inadequacies existed. Engineer can use the result taking action to in line with the actual working conditions in the design of beams and base.Finally the thesis carried on optimized design of the base based on the last part. Using ANSYS optimization module size of the base structure was optimized at the same time guaranteed the structural strength, thereby reducing the weight of the base and saving material.The completion of thesis offers a set of feasible methods for the CAE development of tire molding curing presses. For the CAE aspect, based on the ANSYS software, the thesis shows the process of the tire molding curing presses structure and thermo-mechanical coupling field. Based on the above analysis ,the optimization of the base has been implemented. CAE is the essential power in tire molding curing presses industry.Moreover, the study is still gross in molding, meshing, loading and dealing with boundary conditions. It requires further division, which will be the future direction of research.
