Identification of critical speeds using unbalance response data
 Balda, Miroslav
A new method of the identification critical speeds out of noisy measurements of rotor responses to an unknown unbalance is described. The identification procedure is based on the fitting experimental data by a response of a Single-Imput Single-Output **em. The method yields natural frequencies with dampings of the rotor out of data measured at a certain point of a machine. The result may serve to estimating planes of modal components of an unbalance.

Influence of plastic zones on the stress waves propagation
 Valeš, František ; Laš, V. ; Lašová, V. ; Červ, Jan
Influence of plastic zones in a thin bar on the elastic waves propagation. Plastic deformations are created by superposition of compression pre-stress created in the middle part of the bar, the other end of the bar is built in. Followed is the pre-stress after interaction with the primary wave.

Povrchové vlastnosti nanokompozitů silika/epoxy nátěrů
 Bláhová, O. ; Špírková, Milena ; Farkačová, T.
This contribution deals with the determination of mechanical properties of hybrid organic-anorganic epoxy-based coatings prepared from functionalized organosilicon precursors, oligomeric di- or triamines and colloidal silica particles or montmorillonite.

Mechanical properties of organic - inorganic nanocomposites coatings
 Farkačová, T. ; Bláhová, O. ; Špírková, Milena
The contribution deals with the determination of tribological properties of hybrid organic-inorganic epoxy-based coatings on tribometer by method pin-on-disc. The friction coeffiecient and wear resistance were monitored. Examined specimens were prepared from functionalized organosilicon precursors, oligomeric di- or triamines and colloidal silica particles. The products are the result of two independent reaction mechanisms: the sol-gel process and the epoxy-amine addition reactions.
