Rheological Properties of Grease and Grease Lubricated EHD Theory

An algorithm by fitting apparent viscosity test data to obtain a four-rheological-parameter constituent equation of grease is advanced. Makinguse of weighted residue method, derived is the equivalent reynolds equation. Numerical complete solution is acquired adopting Christensen's rigid stamp model. Iteration scheme is employed until finally the non-Newtonian effect parameter is satisfactorily converged. The agreement between theoretical and experimental results is good.
