An experimental investigation has been conducted into the response of elastohydrodynamic (EHD) lubricants subjected to the high shear rates and pressures encountered in EHD lubrication and over comparable time scales. New techniques have been developed to measure the dynamic compressibility of EHD lubricants at pressures as high as 1 GPa, and the response to dynamic shearing at shear rates as high as 4.0 x 104 sec-1, over timescales of about 10-4 sec, and for a range of initial temperatures.
