单点接触

以单点接触问题为例研究了有摩擦接触问题的几个特点，给出了这类问题出现不唯一解的条件。

In this paper , some properties of the frictional contact problems are researched by means of a simple one node contact problem , and the conditions for ununique solutions are discussed .

在轮轨单点接触计算分析的基础上，建立锥形踏面车轮的轮缘贴靠钢轨形成两点接触的计算模型，应用有限元参数二次规划法分析这一弹塑性接触问题。

Based on the analysis of one-point contact of wheel and rail , the computational model for two-point contact resulting from cone-tread wheel flange close to rail is established . The problems between wheel and rail are analyzed by using the finite element parametric quadratic programming .
