To improve the application simplicity of the research outcomes of fixed joint interface characteristics from mechanical structural numerical analysis, we proposed a parameterized model of a fixed joint interface based on virtual material. Based on the Greenwood-Williamson contact model, Hertz-Mindilin contact theory, characteristic study of fixed joint interface in the unit area, and considering the impacts of various factors of contacting surfaces, we obtained the virtual material parameters of a fixed joint interface: Elastic modulus, Poisson’s ratio, thickness, and density. Focusing on a mechanical structure with bolt connections, we carried out a numerical analysis of the structural deformation under various loading applications, and compared the analysis results with experimental measurements to validate the feasibility and accuracy of the virtual material parameters of the fixed joint interface. This research lays a foundation for further study of the whole character of mechanical structures.
