Stabilization of the Titanium Vibration Damping Wires in the Steam Turbine Blades System

Damping wires are usually used for damping of vibration blades in the steam turbines. Chromium steels or titanium alloys are still applied materials for producing the vibration damping wires. In this paper the stabilization method of the titanium vibration damping wires in the steam turbine blades system is performed. Microstructure and mechanical properties of the damping wires made of WT3-1 titanium alloy after cold and hot bending processes were presented. Analysis of the investigation results cold and hot bended vibration damping wires suggest, that stabilizing by hot bending of the titanium wires in the steam turbine blades system can be used in practice with successful.

Abstract

The natural soil used in filling the embankment of the road communications is characterized by the following factors: humidity, porosity, toughness. For certain factor values that describe the soil state is distinguished a certain soil behavior under the influence of the external forces applied through static or dynamic mechanical means.

In this study are presented the numeric simulation results of the soil-compactor interaction based on the complex and nonlinear rheological model proposed by the author in the result of the elaborated doctorate thesis, that follows the real soil characteristics (elastic, dissipative and plastic) on those of the compaction equipment (with a single vibrating roll). The model was harmonised and granted in accordance with the results obtained from the processing of the experimental data. For the simulation model was used the specialized software package Matlab (Simulink, SimMechanics). The obtained results revealed the real behavior of the equipment and its action on the compacted soil.
