Application of finite element analysis in local stability check of main girder of bridge crane

The introduction of skin sub-stiffening features has the potential to modify the local stability and fatigue crack growth performance of stiffened panels. Proposed herein is a method to enable initial static strength sizing of panels with such skin sub-stiffening features. The method uses bespoke skin buckling coefficients, automatically generated by Finite Element analysis and thus limits the modification to the conventional aerospace panel initial sizing process. The approach is demonstrated herein and validated for prismatic sub-stiffening features. Moreover, examination of the generated buckling coefficient data illustrates the influence of skin sub-stiffening on buckling behavior, with static strength increases typically corresponding to a reduction in the number of initial skin longitudinal buckle half-waves.

On the basis of analysis of the existing problems in the bridge crane of today's society, bridge crane girders were modeled and calculated by using three-dimensional design software, then discussed its finite element analysis. It turns out the research and analysis of the main beam in load in static and dynamic conditions. Through a comparative study of displacement diagram and stress-deformation diagram in the case of loading inertia force or no inertia force, it provides important reference for the bridge crane design, optimization, and lightweight optimization.

A Company

In this paper, we have a development and research combined with the liner replacement manipulator of a company. First, drawing each part of the main girder on ANSYS and assembling them virtually. Next, using the static analysis module of ANSYS to have an integral finite element analysis for main girder. The stress and deformation cloud chart is achieved through this analysis, and the overall performance meets the demand of the design requirements. The analysis result provides the design and improvement of the manipulator with theory basis.

Main Girder

Use the Finite Element Analysis software to numerically simulate the South-to-North Water Diversion Bridge, a prestressed concrete composite box-girder bridge with corrugated steel webs, during the process of cantilever construction. Then research the force condition of the main girder structure during the construction processes. Results indicated that, during each construction process, the bending moment was reasonable, and all sections of the main girder structure were under pressure. The maximum normal stress always appeared around those cross-sections over the main piers, and during the mid-span closure process, the maximum stress appeared around the mid-span segment’s bottom flange.
