The invention discloses a supercharger stator piece analyzing method. The method comprises the steps that a three-dimensional entity finite element model of a supercharger stator piece is built; security evaluation comprising stress intensity analysis and/or thermal fatigue analysis is conducted on the stator piece; a deformation analysis is conducted on the stator piece. According to the supercharger stator piece analyzing method, through the finite element modeling, the stress intensity analysis, the thermal fatigue analysis and the deformation analysis of the stator piece, under the design requirement of higher and higher pressure bearing capacity and more and more complex operating condition, comprehensive and accurate evaluation of the design rationality of the stator piece is conducted.
