载重子午线轮胎有限元网格自动划分程序研究

Study on automatic finite element mesh generation program of TBR tire

基于VisualLISP开发了载重子午线轮胎有限元网格自动划分程序。该程序能够在AutoCAD与Abaqus有限元软件之间建立接口,使用预定数量的割线分割轮胎,可以得到固定数量的节点和单元,适用于结构类似、尺寸略有区别的轮胎有限元网格划分,简化了轮胎有限元网格划分过程。

The automatic finite element mesh generation program of TBR tire was developed based on VisualLISP language. It established the interface between AutoCAD and Abaqus, divided the tire using the defined amount of split line, and obtained the certain amount of nodes and units. It could be applied for the finite element mesh generation with similar structure and slight difference in dimension, and the partition of tire finite element mesh was simplified.
