项目摘要
The purpose of this research project is to obtain better understanding of rheological characteristics of films driven in elastohydrodynamic conditions, in which high pressure high shear rate are applied to cause abnormal film shape. The temperature distributions of oil film and surfaces were measured by an infrared microscope with a high accuracy. The film thickness was measured by white light optical interferometry. In addition, a diamond anvil cell was used to make the phase diagram of lubricant under static conditions. It was found that the temperature rise was quite small in abnormal film shape even in high sliding conditions. The film thickness distribution appeared to change the shape because of solidification as a consequence of high pressure.
该研究项目的目的是更好地了解弹性流体动力学条件下驱动的薄膜的流变特性,其中施加高压高剪切速率导致异常的薄膜形状。采用红外显微镜高精度测量了油膜和表面的温度分布。通过白光光学干涉法测量膜厚度。此外,使用金刚石砧池绘制了静态条件下润滑剂的相图。发现即使在高滑动条件下,异常膜形状的温升也相当小。由于高压导致的凝固,膜厚度分布似乎改变了形状。
