- When designing and calculating through ANSYS software, there exist many solid models that are unable to be simplified as the beam or shell. In order to obtain the distribution of internal force of these structures to guide the optimization design, the paper puts forward a method to obtain the envelope graph of bending moments of solid models through the secondary development of ANSYS software on the basis of the principles of the finite element internal force method. The method is applied to CRTS?ballastless track structure on subgrade to analyze the longitudinal and transverse envelope graph of the bending moments under the action of the design wheel load or the common wheel load with temperature gradient. The method is useful for the optimization design of the ballastless track structure and can be applied to obtain the envelope graph of bending moments, shear or axial force of structures in other fields, which can’t be simplified as the beam or shell element.
