CAD Structural Optimization of Large Cantilever Girders on Cranes
Апстракт
The paper deals with the structural optimization of the cantilever girder. Standard CAD
optimization tool is used for the model of the main girder on a large jib crane. The objective
function is the minimum weight of the girder subjected to the given payload, while constraint
functions are postulated according to the usual structural rules and regulations. The illustrative
example shows an easy way of optimization which can be used in everyday CAD designing practice.
It gives practical recommendations in the selection of variable parameters. The obtained results
indicate that the algorithm is time-saving when compared to the analytical approach, especially
when variability of the section needs to be included in the design.
