摘　　要：热成型过程是一个复杂的生产过程,而制杯机拉伸头的形状结构对于制品的壁厚分布起关键性作用。CAE技术是目前解决产品开发、加工及模具设计中薄弱环节最有效的途径。比较了采用公式法和经验法设计拉伸头的优劣。利用基于有限元法的计算机流体力学(CFD)软件POLYFLOW,分析拉伸头关键尺寸对于壁厚分布的影响。以经验拉伸头为基础,对拉伸头的形状结构进行了优化,为同类制杯机拉伸头形状结构的优化提供了一种新的方法。The process of thermoforming was a complex production process,the shape of the cup making machine＇s plug played a key role for thickness distribution of the product.CAE was the most effective way for solving the weakness which happened in current product development,machining and mould design.The merits of plug design by the formula method and empirical method were compared.The importance of the key dimensions of plug for thickness distribution was analyzed using computational fluid dynamics （CFD）POLYFLOW software based on the finite element method.The shape of plug was optimized based on the empirical shape which provided a new method for optimizing the shape of the similar cup making machine＇s plug.
