A new impact high pressure apparatus was developed with a diamond-anvil pressure cell. Employing this apparatus and sphere deformation analysis method, solidification pressures and estimated traction coefficients of lubricating oils were obtained under milliseconds order impact dynamic compression up to 3 GPa. (Similar pressure in roller bearings) They were a little lower than those under the quasi-static compression condition, but were roughly the same as those. Consequently, although increments of equivalent strain and mean diameter of deformed metal spheres were at most a half smaller than those under the quasi-static compression condition, dynamic high pressure friction properties of solidified lubricating oils in rheological and mechanical viewpoints can be approximated by those under the quasi-static compression condition.

研制了一种新型的金刚石压砧冲击高压装置。利用该装置和球体变形分析方法，获得了润滑油在3GPa以下毫秒级冲击动态压缩下的凝固压力和牵引系数估算值。（滚子轴承中的压力相似）比准静态压缩条件下的压力稍低，但大致相同。因此，虽然变形金属球的等效应变和平均直径的增量最多比准静态压缩条件下的增量小一半，但从流变学和机械学的观点来看，固化润滑油的动态高压摩擦性能可以近似于准静态压缩条件下的那些。
