| Abstract |
Background. On-Board electronic equipment belongs to the class of complex systems with hierarchical branched structure, the construction of which have a significant influence of external mechanical effects in the process of operation. The aim of this work is to develop the design of the installation of monitoring dynamic parameters of elements of designs of onboard radio-electronic equipment, allowing to study its vibrational spectral characteristics.
Materials and methods. It is used in the work of the dynamic wave approach to study the be-havior of elastic structures under non-stationary loading, based on the study of surface Rayleigh waves propagating along the plane boundary of an elastic medium. To increase the frequency of the linearity and reduce the influence of the object of research was used the method of inverse electromagnetic coupling.
Results. Developed a new design of the apparatus for monitoring dynamic parameters of structural elements of the onboard avionics. Feature of offered installation is the possibility of the study of vibration in places of fastening of the structural element, allowing to determine the mutual influence of the element and the ground, and also to evaluate the damping properties of various fasteners.
Conclusions. The developed device gives the opportunity to explore the dynamic parameters of structural elements in the mounting locations to take into account the impact element and the ground, and also to evaluate the damping properties of various fasteners. Obtained by setting the experimental data can improve the reliability of the designed onboard avionics.
