摘要

由于轮胎在成型过程中的几何形状发生了很大变化，因此轮胎成型模拟对拉格朗日有限元代码来说是一个挑战。本技术说明简要介绍了在轮胎成型和固化模拟中使用任意拉格朗日-欧拉（ALE）自适应再网格。ALE概念推广了纯拉格朗日公式，其中时间步长内的解被划分为网格平滑步骤、历史重映射步骤和拉格朗日步骤。在平滑步骤中，通过在不改变数据结构的情况下优化空间网格和材质网格的节点位置来减少网格失真。ALE方法的优点通过一个轮胎成型实例得到了证明。

Arbitrary Lagrangian-Eulerian Remeshing in FE Simulations of Tire Forming

Tire forming simulation is challenging for Lagrangian finite element method codes due to large changes in the geometry of the tire in the course of molding. This Technical Note briefly describes the use of Arbitrary Lagrangian-Eulerian (ALE) adaptive remeshing in the context of tire molding and curing simulations. The ALE concept generalizes the pure Lagrangian formulation, where the solution within a time step is split into a mesh smoothing step, a history remapping step, and a Lagrangian step. Mesh distortion is reduced in the smoothing step by optimizing the node positions of spatial and material meshes without changing the data structure. The advantage of the ALE approach is demonstrated by a tire forming example.

期刊介绍： Tire Science and Technology is the world"s leading technical journal dedicated to tires. The Editor publishes original contributions that address the development and application of experimental, analytical, or computational science in which the tire figures prominently. Review papers may also be published. The journal aims to assure its readers authoritative, critically reviewed articles and the authors accessibility of their work in the permanent literature. The journal is published quarterly by the Tire Society, Inc., an Ohio not-for-profit corporation whose objective is to increase and disseminate knowledge of the science and technology of tires.
