| Abstract: | The hurt principle of the impact between RBC and impeller in the rotated impelled blood pump is studied by using the theory of thinner sphere shell and the theory of liquid drop.The impact stress equation and the extreme stress value of the impacted RBC are presented.The process simulation of the impact is carried out by using ALE finite element method.The RBC variation of the shape and stress at different impact speed are analyzed.The critical impact speed is obtained,and the result is proved by experiment. |
