Digital simulation of load-bearing structures with movable cargo carts

Abstract

The process of digital simulation of the design parameters of load-bearing structures when moving a cargo cart on them is developed on the example of a load-bearing beam of a crane (bridge. gantry, ...). This process includes three main stages. The first stage is the creation of appropriate mathematical multiparametric equations for automated simulation of: the values of reactions in the supports of the crane load-bearing beam; bending moments; transverse forces; displacements; beam deflection angles and maximum stresses at different positions of the cargo cart on the crane beam. The second stage is the creation of appropriate computer models in the Mathcad system using an effective functional programming language built into the system with a graphical representation of the simulation results depending on the location of the cargo cart on the load–bearing beam of the crane. The third stage is the animation simulation of the studied parameters, both for each parameter individually and all together.
