Концепция и метод диагностирования печатных узлов с использованием встроенных эмуляторов вибрационных колебаний

Тихонов А. Н., Увайсов С. У., Иванов И. А., Лышов С. М.
In the paper has been proved the actuality of solving the problem of vibratory diagnosis of printed board assembly. Also has been developed the method of diagnosis of mechanical defects of electronic means, which is based on a new approach to give harmonious effect on the printed board assembly or construction elements. The peculiarity of the suggested approach is using as a source of vibration the vibro emulators (piezoelements), integrated on the printed board assembly. In accordance with the developed method, the effectiveness of diagnosis at the stage of design is maintained through the mathematical modeling of various technical conditions of equipment including various defects found. In the future the results will be compared with the received diagnosis information (experimental data about the vibrating influences). For the quantitative assessment of the results of work the paper offers similarity ratio. The value of similarity ratio shows compliance to the real mechanical characteristics of the fixed defect. Using of vibro emulator allows to control electronic means directly during the maintenance without carrying out of additional time-consuming works.
