The analysis of the stresses and strains state of the strength structure of a rolling bridge for increasing its solidity

摘要

The paper's purpose is to analysis the stresses and strains state in the strength structure of a rolling bridge, presenting a fast and evaluated computer aided solving method for complex static indeterminate structures. The analysis of the stresses and strains state of the strength structure of a rolling bridge for increasing its solidity in exploitation is made using the calculation software with finite elements COSMOS/M. The research performed allows the evaluation of the stresses state, pointing out the critical areas and measures which are imposed in order to increase the solidity and bearing capacity of the strength structure for the rolling bridge. The results we have obtained allowed us to make up a study about the dimension optimization of the strength structure in order to design the rolling bridge. Thus, the material use could be reduced without exceeding the limits of the most appropriate resistance.
