Abstract

Cranes are mainly used for lifting weights everywhere. When desigining cranes, several factors must to be takan into consideration: weights, shocks, wind and ground. It means that design process requires very accurate calculations and several verifications. To shorten design process, a lot of metohods can be used. The use of the numerical method gives the solutions in short time. The main method used is Finite Element Method (FEM). This method gives designers an exact overview of stress and strain which occur in structures under loads. The aim of the study is to determine the state of stress occurring in the structure of Damen Crane Metalna SA Galati ,which can lift and manoeuvre the block sections of the ship up to 320 tons. This analysis is made up with the help of the FEMAP software which enables us to make evolved finite items – shell-type and beams. As a result, it has been seen that FEM is the most practical and easy to use method during the design process.
