摘要

The lubricating oils solidify at quasi-static high-pressure as the amorphous or glassy solids are verified by a number of studies. However, solidification of lubricating oil under the dynamic condition as the rolling bearings and the traction CVT is not clear. The high-pressure short time solidification of traction fluids is examined by the analysis of dent after the impact tests and AE analysis under impact loads. The intensity of each impact collision is measured by means of an acoustic emission (AE) sensor. The dimensionless AE r.m.s value is investigated by based on phase diagram of testing oils. It was recognized the solidification of oil under the dynamic high-pressure condition almost corresponded to the static condition.
