Stress-strain analysis of crane truss loaded by a force with varying position
Cabaj, Gabriel ; Fuis, Vladimír (referee) ; Vaverka, Jiří (advisor)
The bachelor thesis deals with the stress-strain analysis of the truss of a gantry crane. The theoretical part clarifies the basic concepts of statics, elasticity and strength. The concept of influence lines and its use for solving stress-strain analyses of structures with variable position of the loading force is further presented. The practical part deals with a model 2D example, specifically, the design of a cross section for a simplified model of a gantry crane, which is represented by the truss structure. The results for trusses with different degrees of static indeterminacy are compared. Subsequently, the analytical results are verified by the numerical solution in ANSYS software. In the last analysis, a 3D model of a gantry crane with realistic parameters from available sources is created. Finally, the stress-strain analysis of the gantry crane is performed considering the variable position of the loading force.
