基于ANSYS的2根拉索平行钢丝接触问题有限元分析

Finite Element Analysis on Contact Problem between Two Parallel Stay-cables Steel Wires Based on ANSYS

由于2根钢丝接触问题可以作为整个拉索断面平行钢丝间接触问题的简化,故在用ANSYS有限元方法分析整个拉索断面平行钢丝排列模型的接触问题之前,运用经典理论解和ANSYS有限元方法对2根拉索平行钢丝间接触问题进行了较为详尽的分析,确定出了两根钢丝间的接触宽度、在接触面上产生的最大接触应力及分布等主要参数.同时,将2种分析方法得出的结果进行了对比,表明用ANSYS有限元方法求解接触问题是可行的,其求解的准确性和精度能够满足要求.

Contact problem of two steel wires is the simplest one of contact problems, so contact problem of two parallel steel wires of stay-cables is analyzed in detail using both the classic theoretical solution and the ANSYS finite element software before contact problem analysis of the parallel wires of the whole cable sec- tion by the ANSYS finite element software. Some major parameters, such as contact width, maximum contact stress and distribution of the maximum contact stress between two steel wires are detelmined. By comparing the results of both methods, we can find that ANSYS is feasible to solve the contact problem and the accu- racy and precision of this solution can meet our requirements.
