| 摘 要： | 以推力球轴承的赫兹接触问题为例,介绍ANSYS软件的接触分析功能和建模的方法,基于ANSYS软件面-面接触方式中的柔-柔接触类型计算出接触区域的最大接触应力和变形,并对比了赫兹理论解,指出网格局部细化是影响计算精度的主要原因.研究表明,提出的这种方法是正确的,为分析赫兹接触问题探索出一种新途径.

| Abstract: | Hertz elastic contact problem of the thrust ball bearing is analyzed as an example in this paper based on software ANSYS.Contact function and FEM building technique of the software are introduced.Maximum contact stress and deformations are got by using flexible-to-flexible surface-to-surface contact elements of the software.In comparison with the results from FEM and Hertz theory,it shows that the local mesh refinement of the FEM is the major factor that affects the calculation precision.The result proves t... |
