基于APDL的叶脉参数化建模与有限元分析

Parametric Modeling and Finite Element Analysis of Leaf Vein Based on APDL

为了探索植物叶脉对滚动接触摩擦副表面摩擦磨损性能的影响,这里基于APDL参数化设计语言,以叶脉为研究对象,对ANSYS软件进行了二次开发,实现了叶脉的有限元参数化建模。同时,利用ANSYS/LS-DYNA求解器、LS-PREPOST后处理器对“滚子-叶脉”系统进行了显式动力学分析。结果表明:应用APDL编程和ANSYS的二次开发,可以实现叶脉有限元参数化建模和动力学分析的全过程。这为进一步研究叶脉对滚动接触摩擦副的影响机理提供了思路,也为叶脉拓扑结构的优化奠定了基础。

To explore the effect of plant veins on the surface friction and wear performance of rolling contact friction pairs,in this paper,based on APDL parametric design language,taking the vein as the research object,the ANSYS software is redeveloped,and the finite element parametric modeling of vein is realized.Meanwhile,the explicit dynamic analysis of the“roller-vein”system is carried out by using the ANSYS/LS-DYNA solver and the LS-PREPOST post processor.The results show that the whole process of finite element parametric modeling and dynamic analysis can be realized by using APDL programming and ANSYS secondary development.This provides a way to further study the influence mechanism of leaf vein on rolling contact friction pair,and lays a foundation for the optimization of leaf vein topology.
