Abstract

The article focuses on proposing an efficient analytical method for calculating Euler angles of rods in reticulated shell structures to improve finite element analysis accuracy and machining precision. It derives specific Euler angle formulas for cylindrical and spherical reticulated shells, relating these angles to geometric parameters such as azimuths, longitudinal distances, and inclination angles of rod endpoints. Numerical examples involving cylindrical, spherical, and hyperbolic paraboloid reticulated shells demonstrate that the proposed method achieves a close fit between rods and curved surfaces, validated through finite element models developed in ANSYS software. The approach offers a direct, accurate alternative to labor-intensive manual extraction methods used in commercial software, enhancing computational efficiency and structural modeling fidelity for complex curved shell designs.
