摘要
为解决现有直压硫化技术中电磁感应加热不能完全满足轮胎硫化过程的需求,使用COMSOL软件分析鼓瓦内部的磁通密度及温度分布,并设计了电磁感应线圈的新型排布方式。通过仿真分析对比发现,将单根电磁感应线圈分成多段小型线圈置于鼓瓦中,有利于提高轮胎的升温速率和整体温度的均匀性。在鼓瓦中部添加电磁感应线圈可为轮胎胎冠处硫化提供有效热源,更能满足实际硫化需求。根据新型排布方式下在停止加热后轮胎各面的温度趋势特点,提出采取间歇式加热的工艺,并根据温差调整电磁感应线圈的频率,最终达到温度的动态平衡。
In order to solve the problem of electromagnetic induction heating in existing direct-pressure vulcanization technology being unable to fully meet the heating requirements of the tire vulcanization process,COMSOL software was used to analyze the magnetic flux density and temperature distributions of the drum tile,and a modified electromagnetic induction coil has been designed.Through simulation analysis and comparison,it was found that dividing a single electromagnetic induction coil into multiple sections and placing them in the drum tile improves the heating rate of the tire and the overall temperature uniformity.Our modification provides an effective heat source for the vulcanization of the tire crown by adding an electromagnetic induction coil in the middle of the drum tile,which can better meet the actual vulcanization needs.On the basis of the temperature trend characteristics of all sides of the tire after the heating was stopped,it is proposed to adopt an intermittent heating process in which according to the temperature difference,the frequency of the electromagnetic induction coil can be adjusted to achieve a dynamic balance of temperature.
