The Finite Element Analysis of Truss Beam Structure Based on ANSYS

The structural characteristics of the truss were introduced, and the force status of its bars was analyzed and the combination condition of loading condition for analyzing the strength of the truss was determined. This would transfer the internal complex stress state of abdominal girder withstanding the pressure into the simple compression stress state of truss rods, making it intuitive for us to know distribution and transfer of force, and then facilitating the analyzing of the structure. For example, for Pipe belt conveyor case through the establishment of the finite element model of the truss, the paper analyzed the stress, strain and displacement of its main bars while the truss being at various combination of loading condition. The results showed that: ANSYS could offer theory basis for optimization designing truss structure.
