Modelling and simulation research on the metal structure of bridge cranes

Abstract

The carrying metal construction is the most metal-intensive part of overhead cranes and is often subject to optimization and mass reduction. The objective of this project is to reduce the structural mass of a real-world double girder overhead crane, produced by Kranostroene Engineering – Sofia, through the use of modern computer modeling and simulation methods and applications. Following closely the established theoretical foundations and engineering checking schemes the structure mass reduction must be verified by structural static stress simulations. So, for the fulfillment of the project objective, the following tasks will be completed: - Accumulating specific awareness of modern computer modeling and simulation tools and applications, such as SolidWorks, ANSYS, Workbench and the Finite Element Method - 3-D modeling and static structural simulations of a double girder overhead crane in order to establish its detailed 3-D structural response. This includes static stress analyses, frequency analyses, comparison with the well-known theoretical foundations and the Euler-Bernoulli formulations. - Generating models of reduced crane mass. Perform 3-D modeling and structural simulations of the static structural response of the new designs and provide evidence that they conform to standard requirements and do not deviate significantly from the original crane response.
