中文摘要: |
研究冷却工艺对轮胎外缘尺寸及性能的影响。结果表明:自然冷却速率高于硫化后充气冷却速率,但硫化后充气冷却轮胎的尺寸均匀性、径向刚性和耐久性能均较高;延长硫化后充气时间、降低硫化后充气终点轮胎温度,有助于降低轮胎尺寸收缩率;单根帘线的张力需大于初始冷却温度下骨架材料的热收缩应力,随着硫化后充气压力提高,轮胎外缘尺寸呈增大趋势;硫化后充气轮辋宽度对轮胎的外缘尺寸影响较小;随着出模时间的延长,轮胎外缘尺寸减小,需要控制出模时间。 |
英文摘要: |
The effect of cooling process on the peripheral dimension and performances of tire was studied.The results showed that the natural cooling rate was higher than that of post-cure inflation cooling,but the size uniformity,radial stiffness,and durability of the post-cure inflation cooled tire were higher. Extending the post-cure inflation time and reducing the tire temperature at the endpoint of post-cure inflation could help reduce the tire size shrinkage rate.The tension of a single cord needed to be greater than the thermal shrinkage stress of the skeleton material at the initial cooling temperature,as the post-cure inflation pressure increased,the peripheral dimension of the tire showed an increasing trend.The width of the post-cure inflation rim had little effect on the peripheral dimension of tire.As the demolding time prolonged,the peripheral dimension of tire decreased,and it was necessary to control the demolding time. |
