Abstract
To model the vibration fields established in composite multidimensional machine structures, distributed impact elements are used, which take into account the wave processes occurring in colliding subsystems (shock pairs), which, in turn, quite often determine the structure of these fields. Two types of corresponding models are considered: with simple and complex structures. Specific examples of dynamic models are given. The results of the analysis are given.
Highlights
Modeling of vibration fields in machine structures is an important and actual problem, since their features and structure on the one hand determine the vibratory activity of machines and machine systems, and on the other hand can determine many aspects of the useful use of vibration processes
One of the most important factors in the formation of the vibratory field is the systematic collisions of structural elements that generate broadband shockvibrating processes [1, 2]
It is shock-vibrating processes that are the determining factors that influence the structure of vibratory fields
Summary
Modeling of vibration fields in machine structures is an important and actual problem, since their features and structure on the one hand determine the vibratory activity of machines and machine systems, and on the other hand can determine many aspects of the useful use of vibration processes. One of the most important factors in the formation of the vibratory field is the systematic collisions of structural elements that generate broadband shockvibrating processes [1, 2]. Note that the selection of two cases is made for convenience They have a close nature, they are described in many ways similar models and they exhibit a manifestation of similar dynamic effects, perhaps the main one is the emergence of "claps" (the appearance of synchronization of shocks at remote points). It is systems of two types will be considered in the article
