  • The traction of a new aviation lubricating oil was measured on a self-made test rig.The calculating formulae of the rheological parameters of the oil such as Erying characteristic stress,shear stress limit,and shear elastic modulus were given under the condition of the high shear rate in elasto-hydrodynamic lubrication.Then the constitutive equation of this oil was determined,and the calculating formulae of the oil traction was given and verified by test.The experimental results show that the behavior of new aviation lubricating oil behaves as the visco-elastic fluid,the calculated traction coefficients agree fairly well with the measured data.The method of the traction force calculation can be used to guide the lubrication analysis in engineering computation.
