%X A new five-parameter rheological model was presented based on the Evans-Johnson rheological model, and the traction coefficients calculated by the Evans-Johnson rheological model and the five-parameter rheological model were compared with the experimental traction coefficients. The computed results show that the traction curves predicted by the five-parameter rheological model agreed is high. When the thermal effects inside the contact zone well with experimental curves and the predicted precision played strongor role, the traction coefficients predicted by the five-parameter rheological model were more accurate than those predicted by the Evans-Johnson model, and the temperature in oil film predicted by the five-parameter rheological model was higher than that predicted by the Evans-Johnson model. The traction coefficients predicted by the two models were equally accurate when the thermal effects were not significant. The five-parameter rheological model have successful solved the problem for predicting fraction coefficient with high precision when the thermal effects are significant, while the Evans-Johnson rheological model has low prediction precision at the same conditions.
