Abstract: As the core part of the mine hoist, the mechanical analysis and calculation accuracy of the head sheave shaft is related to the safe production of the whole mine. The mechanical properties of the head sheave shaft is analyzed by the one-dimensional beam theory. First of all, the second-order displacement field of the element is established using the Carrera Unified Formulation. Then the mechanical model of the head sheave shaft was established by employing the principle of virtual displacement. At last, the accuracy and the practicability of the one-dimension high-order model is demonstrated by comparing ANSYS simulation results. Compared with the traditional beam theory, this method has obvious superiority, which can provide theoretical support for the design of the head sheave shaft.
