    功能塊在模頭口模中一般是附屬在主型材上,但它對主型材熔體在口模中的流動以及型材的整體質(zhì)量卻有著不可忽視的影響。
  • Abstract : in order to eliminate the product defects such as deformation , corrugation and rupture , the authors put forward the principle of flow rate uniformity for the design of rubber and plastics profile extrusion dies . on the basis of this principle and through the rheologic analysis of some actual cases , the design procedure is demonstrated
    文摘:為解決擠出制品的扭曲變形、起皺、破裂等問題,本文提出了橡塑異型材擠出口模設(shè)計的流率平衡原則,并據(jù)此原則通過對具體例子的流變學(xué)分析,提出了口模設(shè)計方法。
  • A new method should be discovered to design the function block . the thesis is based on the rheology and hydrokinetics of the polymer melt , and calculates the velocity in the die by fem simulation , and provides die design with theory proof . according to the existed theory , i summarize and conclude the fem formula of the polymer flow , and then write the program to calculate on the computer
    本論文中功能塊結(jié)構(gòu)的研究,是以熔體的流變性以及流體動力學(xué)理論基礎(chǔ)上,對在口模中的熔體進行數(shù)值模擬,計算出熔體在口模中的流動參數(shù)(主要是速度的分布) ,從而可以科學(xué)的對功能塊幾何結(jié)構(gòu)進行優(yōu)化。
