具有聚合物滑动层的流体动力轴承能够在恶劣条件下运行，主要是由于聚合物的良好特性。本研究的目的是评估两种类型的聚合物复合材料层的表观杨氏模量用于滑动表面的流体动力轴承，作为温度的函数。杨氏模量是根据对从推力轴瓦获得的样品进行的压缩试验来评估的。测量伴随着额外的有限元计算，再现experiment.The结果中提出的文件证明，所研究的类型的复合材料层的表观杨氏模量显着依赖于温度和它们的值不同于现有的聚合物数据中的信息。
Hydrodynamic bearings with a polymer sliding layer are able to operate in severe conditions, mainly due to favorable properties of the polymers. The goal of this research was to evaluate apparent Young׳s modulus of two types of the polymer composite layers used for sliding surfaces in hydrodynamic bearings, as a function of temperature. The Young׳s modulus was evaluated on the basis of compression tests carried out on samples obtained from thrust bearing pads. Measurements were accompanied by additional FEM calculations, reproducing the experiment.The results presented in the paper prove that apparent Young׳s moduli of the studied types of the composite layers depend significantly on temperature and their values differ from existing information in available data on polymers.
