    Experience Formulating and Solving Inverse Problems for Strength Design of Electronic Equipment
    (2014-08-20) Goroshko, Andrii
    The paper shows the results of formulation and solution of inverse problems for strength compounded elements electronics. Considered and studied real construction - micro-module. A parameter identification of a mathematical model, as close to the real conditions of the structure is offered. Decomposition of a mixture of probability distributions experimentally obtained values of destructive forces in the tests carried out. The tolerances of valid values of the mathematical model by solving the optimization problem are calculated. For the case where the physical and mechanical characteristics of the elements do not correspond to those found with the limits of tolerances and do not provide the structural strength, proposed some solutions to this problem. In this way, there is a selective assembly.

    Identification of Physical and Mechanical Properties of Compound by Solving Inverse Problems
    (Druskininkai, Lithuania, 2013) Goroshko, A.V.; Royzman, V.P.; Bubulis, А.
    The paper presents a method of identification of physical and mechanical characteristics of the compound (calculated and experimental test method parameters). The idea of the method is that the studied material is connected with other materials, the characteristics of which are well known and differ from the characteristics of the material. Desired physical and mechanical properties should be considered unknown in the proposed calculation model, and the values of the parameters of trial constructions that can be measured accurately with experimental methods in the process of product operation, as well as characteristics of test materials and geometric dimensions of proposed structures are suggested to be placed in the same model as input information.
