表状态

An Improved Procedure for Component Life Estimation with Applications,Local Strain Approach is used to determine the amount of fatigue damage from each harmonic component. The resulting cumulative damage is evaluated using Miner’s law, to provide an estimate of component life under given stress and thermal load conditions. Several examples which describe the application of this procedure are given.

Analysis of Rotors in Bearings,the first critical speed. Then the start-up and shut-down behaviour of a rotor is described. The influence of bearings also is studied using the Jeffcott model. A simple model shows the influence of bearing damping. In the last section the main aspects of unbalance behaviour of multi-bearing systems are discussed.

ANTIC

Principles of Balancing and of Balancing Machines,s are described. Plane separation and the need for Wattmeter filtering are discussed in relation to balancing requirements and signal conditioning. Larger rotor facilities and automated production facilities are described.

Computer Analysis of Rotor Bearing Systems,ied out by keeping account of the interaction with a supporting structure of same (foundation, casings, etc.). Together with the structure of the package, this paper is aimed at illustrating the mathematical model used for static and dynamic analysis.

BYRE

Torsional Dynamics of Power Transmission Systems,useful formulas for natural frequency analysis. Damper design principles are reviewed, with criteria for suppression of troublesome modes. Two Case Histories from practice are discussed, indicating the diagnostic procedure used and the vibration suppression methods in each case.

Infant

Flow Path Excitation Mechanisms for Turbomachine Blades,scribed, with details of analytical contributions to these areas. Experimental procedures for measurements of blade non-steady forces in the laboratory and in the field are described. Selected test data are included. Recent developments using the rotating water table approach are reviewed.
