The invention provides a simulation analysis method for a cigarette case made of a composite paper material, and the method comprises the steps: constructing a paper model in a multi-layer composite modeling mode, and enabling the number of layers of modeling to be larger than the number of layers of paper in an actual indentation and bending test, the contact failure between layers in the paper model comprises normal failure stress and shear failure stress; characterizing anisotropic characteristics of the paper model by defining material parameters in the MD direction and the CD direction, and performing benchmarking on the paper model and the paper material; and applying the marked paper model to a cigarette case model, and verifying the accuracy and stability of the cigarette case model structure through a crushing test and a cigarette case switch test. The standardized modeling process for cigarette case paper material development and application fully considers the composite characteristics and anisotro
