On the example of the strength static calculation of assembly table, there is made a comparative analysis of the accuracy and labour-output ratio of the standardized approach, regulated by OST 92-8767-76, and the finite element calculation in FEMAP using NASTRAN linear solver. The author gives the estimation of labour-output ratio and the relative error of determining the location and magnitude of maximum stress in the structure. It is shown that the finite element calculation must be included in industry standards.
