Paper Abstract

The vibrodiagnostic of electronic engineering products, used in systems of automatic control of flying apparatus, to which quartz resonators concern, serves at improvement of optimum designs in a given range of working vibrations. The operation an onboard of a control system shows the increasing requirements not only to reliability and stability of their work, but also stability to vibrating and climatic influence. So, for example, many designs of quartz resonators should maintain vibrating overloads up to 5 g in a range from 5 Hz up to 10 kHz. The vibrodiagnostic and forecasting of reliability of quartz resonators for onboard a control system came true with the help of the holographic module, which consists of two blocks; the measuring block and block of data processing on the basis of the personal computer. The resonant frequencies, were defined by a method 'real-time,' the definition of overloads on the quartz resonator was conducted by a method 'real-time' and 'time-averaging.' Existing various optical methods of research of fluctuations did not allow to register longitudinal and planimetric styles of fluctuations whereas the vector of displacement is directed in parallel to a plane of a quartz piezoelement. A method of a holographic interferometry has allowed supervising not only transverse, but also longitudinal and planimetric styles of fluctuations of quartz resonators. Four patents of Russia protect the constructive elements of the developed complex holographic module. The given module was used for a vibrodiagnostic of quartz resonators in a range of own frequencies of fluctuation from 5 Hz up to 10 kHz with an overload up to 5 g, thus were eliminated constructive and technology factors, influencing on shift of own frequencies of quartz resonators in low-frequency area.
