Abstract

Purpose. The results of the optimization investigation and the rational projects of the bearing structure of ballast leveling machine SPZ-5/UA are brought in this paper. The necessity of realization of structural optimization of the investigated machine is reasonable. Methodology. The statement of the optimization problem is executed: the beam cross-section square is taken as the objective function; the allowable stresses criterion is taken as the constraint in this problem statement. Findings. The simplified FE-model of structure of machine is worked out. The optimization problem of double-T cross-section is considered as a test case. For this problem we can obtain the analytical and numeral solutions. Originality. The rational designs for the bearing structure of the investigated machine are brought with the increased consumption of material with preservation of durability characteristics. Practical value. The optimization investigation is executed for bearing structure of the ballast leveling machine SPZ-5/UA by the use of the numerical structural optimization procedure. The obtained rational structural projects are compared to the structural projects with standard double-T cross-sections. It is shown that the use of structural projects with standard cross-sections makes it impossible to obtain the better structure as compared to the rational project. As a result the rational structural project of the ballast leveling machine is obtained, which have the sufficient safety factor. The cross-section of the main longitudinal beam of the bearing structure of leveling machine is decreased on 73%.
