We proposed a method of deformability evaluation based on the deformation and movement by the dynamic behavior of erythrocytes in the oscillation flow field. However, to evaluate the deformability of variously changing erythrocytes according to the individuals and disease state was considered necessary to improve the accuracy of the model.Therefore, we examined the degree of freedom and the mass ratio of the mathematical model for the purpose of improving the accuracy of the modelin the previous study.Simulation based on the parameter identification resulted that the viscoelastic 2 elements with 3 degree of freedom model with particular mass ratio became waveform close to the erythrocyte's deformation amount ⊿L of experimental results．However, the improvement of the phase shift of the erythrocyte -e's center of gravity displacement ⊿G had a limit．Also, the viscoelastic 3 elements with 4 degree of freedom model was found that the phase shift of erythrocyte's center of gra -vity displacement ⊿G between experimental result and simulation result is eliminated．However, the erythrocyte's deformation amount ⊿L has become monotonous in this model as compared to the previous study．From the above，it improve -ed the accuracy of the viscoelastic 2 elements with 2 degree of freedom model in previous study．
