Modification of technique of structural design of pipeline system taking into account experimental data of a strain-gage testing has been completed. The various ranges of frequency response analysis of the dynamically loaded hydro-gas system’s collapsible pipelines constructions with application of a finite element method nonlinear contact problem has been done. Frequency responses of collapsible pipelines constructions hydraulic system pressure line of a modern airplane before and after modernization on the presented method are presented; decrease of structures dynamic stresses in the operating frequency range. This work continues research of dependence of frequencies of natural vibra-tion and tensely deformed condition of pipeline systems from features of its detail of construction.
the pipeline, frequency response, hydraulic system, resonance, damping, dynamic tensely deformed con-dition, contact problem, finite element method.
