Non-coupled Thermal-mechanical Numerical Simulation Analysis On Tir Segment Mould Warming Procedure

Tire segment mold is the principal equipment for tire vulcanizing. Thetemperature distribution of the mold and the time for heating the mold influencegreatly on tire products’ performance and production cost exactly.Though theapplication of ABAQUS software, this paper,which focus on reducing the mold cavitytemperature difference and shortening the time of heating the mold, takes9.00R20and10.00R20tire segment molds heating process as example and carries out numericalsimulation analysis of heat transfer numerical and stress-strain for segment moldheating prograss. Based on simulated temperature-time data, strain-stress data andtemperature transfer law, improvement schemes which can decrease the tread blocktemperature difference and the time of heating the mold are proposed. The authorcarried out mainly in the following areas of research:(1)Heat transfer simulation of axisymmetric and three-dimensional modeland stress-strain simulation analysis under working load of the9.00R20tire mold werecarried out.(2) According to the law of segment mold’s temperature transmission duringheating process, several schemes to adjust mold’s stracture, such as changing the sizeof middle sleeve’s steam room, changing the size of wear-resistant plate on base plate, changing the flare angle of slide block, changing the type of contact between slideblock and segment and the hot water’s temperature of top heating plate and bottomheating plate, were conducted and the temperature-time data of the caxity wereobtained by using the ABAQUS simulation software, then better heat transferperformance mold structure and technology were determined.(3) Stress-strain simulation analysis of structure improvement which has the mostsignificant effect on heat transfer process was run under working load.(4) Heat transfer simulation analysis of the10.00R20tire mold in heating processwas done. Reference to the changing aspects of the9.00R20tire mold, which influenceheat transfer process obviously, the structure revisions for10.00R20tire mold werecarried out and the heat transfer performance of two mold types was compared throughsimulation analysis.
