This page shows details on the project. The primary projects are displayed together with a list of sub-projects.

Project description:1/ vibration analysis of machines and structures as mechanical systems with concentrated and distributed parameters with deterministic and random excitement from the point of view of passive vibroinsulation at various initial and marginal conditions ? mechanical systems vibration caused by fluid pressure with backstop, which is activating the impact power effect. Fluid thermodynamic analysis from the point of view of exciting power effect identification will be also a part of the solution. Theoretical conclusions will be applied on hermetic refrigerating compressor valves vibroinsulation and on vehicles and trailer vibration. 2/ creation of iteration method of machines and structures mathematical models modification from the point of view of modal and spectral attributes maintenance in the operating conditions; 3/ vibrational diagnostics of location and type of rotary machines and structure failures based on analysis of modal and spectral attributes of equivalent mechanical system ? applied on failures of shafts, blades and structures; experimental verification of theoretical conclusion.
