Abstract

Abstract:

The three-dimensional elastic contact problem with the variable friction model was studied.The contact conditions were imposed along the contact nodes' normal and sliding directions.The program packages for contact solution were designed using FORTRAN language,which were applied to investigate an
example of contact problem with a velocity-correlation friction model.The variations of nodes'contact states and contact forces with sliding velocity were examined.Eventually,the validity of the proposed algorithm and the designed program packages were verified by comparing the computed results with that obtained from the commercial software.

Key words: gear, contact, variable friction model, finite element analysis(FEM)

摘要：

首先对三维弹性接触问题的有限元求解算法进行研究,将接触条件转换到法向与滑动方向组成的局部二维坐标系内进行求解,并利用FORTRAN语言编制接触问题求解的程序包。然后应用该程序包对变摩擦条件下的接触算例进行研究,揭示摩擦因数随滑动速度改变时接触点随接触状态、接触力的变化规律。最后利用有限元软件对计算结果进行验证,证明了算法的有效性。
