| description | To meet the high-precision and efficient simulation needs for the static and dynamic performance of largescale lattice structures，this paper proposes a simulation analysis method for the calibration of tapered beams in lattice structures. Based on the dynamic response of 3D printed specimen，an inverse problem model for the geometric parameters of the tapered beam element is established and solved. For lattice structures with different diameters， the inverse problem calibration of the tapered beam parameters is carried out respectively，and an interpolation model for the geometric parameters of the tapered beam as a function of rod diameter is established. Finally，the effectiveness of the interpolation model for the geometric parameters of the variable cross-section beam is verified for lattice structures with different rod diameters and gradient lattices. Results show that：compared with the solid element model-based simulation analysis model，the simulation analysis model of tapered beam element established in this study not only has comparable dynamic performance simulation accuracy but also significantly improves the efficiency of analysis. |
