【摘要】 通过对中空制品的冷却过程进行分析,建立了冷却过程中的物理模型和传热方程,并以高密度聚乙烯为例,采用ANSYS有限元分析软件进行了模拟分析,得到冷却曲线,对中空制品的冷却过程提出了相应的观点。更多还原

【Abstract】 It established the physical model of blow-molded article and derived the equation of heat transfer existing in the cooling process of hollow article.Taking HDPE as testing resin,it simulated and analysed the cooling process by using ANASYSthe finite element analytic programme,and obtained the cooling curves of the temperature distribution in thickness,as well as put forward corresponding viewpoints to the cooling process of hollow articles.更多还原
