Optimal Design And Thermodynamics Analysis On New Mechanical Elastic Wheel Segmental Mold

Vulcanization is the process of Mechanical elastic wheel mould manufacturing, whether the structure of mould designed properly has a direct effect on the vulcanization quality of mechanical elastic wheel?This paper selects structure design and optimization of mechanical elastic wheel as research object, aims at studying the influence of structure of mould on mould's heat transfer characteristics. It will provide some inference and gist on the optimization design and manufacturing of mechanical elastic wheel.(1) According to the particularity of new elastic mechanical wheel mould, analysis and summary design,material and process requirement, confirm structure of segment mould. The force bearing status and load molds of segment mould has been analyzed. The forcing bearing mold has been established according to the mould's load status in vulcanizing machine.(2) Build the solid mold of different parts of mould by using 3-D solid modeling software and assemble them together. Based on thermal transfer theory, heat conducting equation has been established. get wheel's temperature rise curve.Introduced sulfurization percentage and sulfurization consistency to build sulfurization quality evaluation system. Using sulfurization data of wheel which integrals from temperature rise curves to get global sulfurization quality of wheel. It provides basis data and improving direction of structure optimization of mechanical elastic wheel segment mould.(3) Get the objective function which can represent wheel sulfurization quality, extract design variables, established single goal optimization model of mechanical elastic wheel segment mould,using iteration method to get accurate numerical solution. According to optimization results, diameter of mould changes to 1540 mm,length of medium room changes to 160 mm, thickness of middle top cap changes to 20 mm. Then doing thermal finite simulation again to test the correctness of optimization mold. The results shows that sulfurization percentage has declined by 10.5%, sulfurization consistency has risen by 21.7%.In this paper, a segment mould used to vulcanize new elastic wheel is designed. Simulation software is used to finished thermodynamic analysis, evaluation of sulfurization quality and structure optimization has been done. A whole set of mould can be used to vulcanize wheel has been achieved.
