摘　　要：采用UG建立12.00R20规格光胎与复杂花纹轮胎的三维硫化模型,使用ABAQUS仿真分析了光胎与复杂花纹轮胎在模具内的硫化升温和自然冷却过程。仿真结果表明:忽略轮胎花纹,会使轮胎胎肩和胎面部位的硫化与实际情况存在较大差距;复杂花纹轮胎模型整体硫化升温速度快,自然冷却速度也快;轮胎硫化出模后,两种轮胎模型的胎肩、胎面、三角胶部位的后硫化反应仍长时间在进行。Based on UG it builds a three-dimensional vulcanization model of 12.00R20 smooth tires and complex pattern tires,analyzes the vulcanization heating and mold cooling processes of smooth tires and complex pattern tires in ABAQUS system.The simulation results show that ignoring the tire pattern causes a large gap on the shoulder and tread of the tire between the simulation results and actual situation.The vulcanization temperature of the complex pattern tire increases rapidly as a whole,so as cooling rate when removed from the mold.After the tire is vulcanized,the post-vulcanization reaction of the shoulder,tread,and bead filler of the two tire models is still ongoing for a long time.
