| description | In this paper, we study the methods for calculating beams with skating in the lower belt of both the Ibeam and box sections. Based on the dependences presented in the existing methods, the stress-strain state of
single-beam bridge cranes was calculated at the points
of contact of the wheels of the hoist and beam belt, with
a box section with rolling along the bottom. Box-section
crane cranes have greater rigidity and stability compared to the I-beam section, in addition they allow you
to increase the span without sacrificing the crane's lifting capacity. SolidWorks Simulation also performed a
finite element analysis of the stress-strain state of boxsection beams with skating along the lower belt. The
main advantage of the finite element method is the ability to split into finite elements areas of any shape and,
thus, the ability to calculate the stress and strain fields
in real details, taking into account all their design features, which ensures high accuracy of the calculation.
On the basis of the results obtained, the dependences of
stresses on the thickness of the lower girder beam, the
position of the hoist wheels were studied, an approximating function was constructed, and a simpler engineering calculation method was proposed that allows
one to reduce the number of calculations |
