## 1 Introduction
[31; 32] applied orthotropic anisotropic materials to the shaft-disk rotor structure, and, with the help of experiments and finite element methods, found that the use of composites with a fiber-laying direction of 90\({}^{\circ}\) could significantly reduce the vibration of the rotor. [PERSON] et al. [33; 34] proposed and validated a dynamic model of a flexible functional gradient rotor system with a variable thickness disc and comprehensively analyzed the effects of geometrical parameters, material parameters, and the shape of the disc cross-section on its vibration characteristics. They pointed out that the material parameters would affect the overall vibration characteristics of the system to a certain extent. [PERSON] et al. [35] proposed a modeling method for a graphene nanosheet-reinforced blade-disk system and found that it was possible to use an orthotropic anisotropic material for the rotor structure with the help of experimental and finite element methods. They investigated the impact of graphene nanosheet parameters on the system and concluded that incorporating graphene sheets can enhance the mechanical properties of the system. Furthermore, thinner and larger graphene sheets are observed to increase the structural stiffness. [PERSON] et al. [36] also applied graphene nanosheets and porous copper-metal foams to a rotating shaft-disk blade system and performed resonance analyses and parameter interval uncertainty analyses. The effects of porosity and material parameters were comprehensively explored. In summary, in the application of fiber woven composites, most of the simple components, such as plates, shells, beams, etc., are the macroscopic carriers of the materials, and their kinetic properties are either studied by experimental means or only with a single component as the object of study. There is still a lack of in-depth exploration of the numerical modeling and analysis of the dynamics of the complex coupled structure of the fiber woven materials; in the case of the open-pore structure, the object of study is generally a simple plate and shell structure. There is no focus on the application of simple structures to complex systems. On the whole, the existing studies seldom consider fiber woven composites, weight-reducing holes and shaft-disk rotors in an integrated way, and the modeling method of the fiber woven composite shaft-disk rotor system with weight-reducing holes has yet to be perfected. In view of the above research deficiencies, this paper takes the fiber woven composite material shaft-disk rotor as the research object, adopts the domain decomposition and coordinate mapping technology for the porous disk, and establishes a unified dynamic model of the fiber woven composite shaft-disk system through simple beam and plate theory and the differential quadrature finite element method (DQFEM). The model has been verified by the literature, finite element simulation, and experimental comparison, and has been proven to have good convergence, accuracy, and practicability. The corresponding kinetic study was carried out to investigate the effects of material parameters and hole parameterson the rotor's natural frequency and critical speed, and the conclusions obtained will be helpful to guide the lightweight and vibration-damping design of the shaft-disk rotor.
