Abstract

Abstract Technical rubber or polymer profiles are often extruded while dragging them into a water bath. However, complex or heavy profiles may require additional guiding tools. For example, geometrically complex profiles, such as PVC-window frames, require the use of calibrators for satisfying severe geometric requirements, while heavy rubber profiles, such as D-shape fenders or tire treads, require a conveying belt mainly for being able to achieve the process. Within the context of numerical simulation of extrusion flows, such a guiding tool brings an additional downstream constraint to the kinematic equation which dictates the shape of the extrudate surface. In the present paper, we propose a simple engineering approach for modelling a conveyor belt used in rubber tire tread extrusion, and we apply it to the simulation of the extrusion flow for a 3D non-symmetric profile of a viscoelastic material.

挤压流动模拟中的输送带建模

摘要技术橡胶或聚合物型材通常是在将其拖进水浴中时挤出的。然而，复杂或重型型材可能需要额外的导向工具。例如，几何复杂的型材，如PVC窗框，需要使用校准器来满足严格的几何要求，而重型橡胶型材，如D形挡泥板或轮胎胎面，主要需要输送带才能实现这一过程。在挤出流动的数值模拟的背景下，这种导向工具为运动方程带来了额外的下游约束，该方程决定了挤出物表面的形状。在本文中，我们提出了一种简单的工程方法来建模用于橡胶轮胎胎面挤出的输送带，并将其应用于粘弹性材料三维非对称轮廓的挤出流动模拟。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
