Analytical Calculation and FEM Analysis of Single Girder Bridge Crane Made Out of Hot-Rolled Profiles

What is it about?

Abstract: With the development of science and rapid growth of engineering needs for suitable structural analysis softwares, FEM (Finite Element Method) analysis has become one of themain tools for design process. Combination of hardware and software resources gives complete geometric model of any assemblywith accurate results for research field. At the same time, this approach enables effective realtime data manipulation that reduces design process time to minimum. Practical significance of this design system is reflected in more convenient, faster and safer task completion. Bridge cranes are one of the most widely used cranes for material transport in modern production and they represent complex systems, composed of many subsystems with different coupling characteristics. Empirical design is most often used for crane’s necessary structure calculations and other design parameters that have direct impact on production performance.Bridge girder, as a main component in special machinery equipment, requires accurate perfomance data results like bending stresses and deflections that meet the design requirements. The result of this research is analytical calculation of single girder bridge crane, with determined maximum bending stress and deflection on bridge girder. After calculation is performed, geometric 3D model of single girder bridge crane is created in CATIA (Computer Aided Three-dimensional Interactive Application) software. Geometric 3D model was than subjected to FEM analysis in same software, whereupon results comparison has been done.
