Mechanical stress analysis of port crane based on the condition of temperature field

This paper systematically study the calculative theory of of large-scale port crane´s the temperature field and thermal stress, Use the finite element software ANSYS to mode and analyse the large-scale port crane under the temperature field and temperature stress. Carry out a detailed study to results of the analysis and determine the impact of temperature stress on port crane structure. The analytic results show the temperature impact has a non-negligible effect on the structural strength of the port crane, which is likely to result in the main factors of the local structure´s cracking.
