Evaluation of the VPI & SU fluid film bearing test rig
… for predicting the performance of fluid-film bearings. This work presents an initial evaluation of a test rig for verifying such codes. This presentation includes background information on the techniques and terminology of fluid-film bearing analysis and two basic approaches to experimental …

The development of a rule based expert system to automate the digital analysis of condition monitoring parameters captured on rolling element bearings subjected to simulated failure
… of a rule based expert system to diagnose bearing failure. Firstly it covers the proposal of a generic, expert system based industrial condition monitoring system. It then discusses in more detail the development of a specific aspect ofthe system, viz. the analysis of rolling element …

Development of a Novel Performance Index and a Performance Prediction Model for Metallic Drinking Water Pipelines
… evaluate and verify the predicting results. Lab testing of several pipe samples is also used to evaluate the model. The testing consists of a ring bearing test which is used to calculate the rupture modulus of the pipe. Comparing the original vs. the current rupture modulus can determine the …

Wireless Sensors for Condition Monitoring Applications Operating in Complete Metallic Environment
… may be attached to critical components such as bearings, gears, mechanical seals, shafts etc. for measurements. These sensors however are often inadequate solutions as wired sensors are dicult to mount on rotating components, especially in millimeter-size spaces that may exist in some of these …

A review of vibration signal processing techniques for use in a real time condition monitoring system
The analysis of the vibrations produced by roller bearings is one of the most widely used techniques in condition determination of rolling element bearings. This project forms part of an overall plan to gain experience in condition monitoring and produce a computer aided vibration monitoring system …

Heterogenkatalysierte elektrophile Addition am Beispiel der Hydratisierung von Ethylen und Alkoxylierung, Acyloxylierung von Oleochemikalien
… were impregnated with phosphoric acid and tested in the “ethanol plant” at 50-70 bar and 270-300°C. The performance of the catalysts and the change of the catalysts in the reaction were subject of this investigation. The performance of the catalysts was monitored by measuring the ethanol …

Measured and Predicted Rotor-Pad Transfer Functions for a Rocker-Pivot Tilting-Pad Journal Bearing
… and damping coefficients for tilting-pad journal bearings (TPJBs) to measurements. Most have found that direct damping is consistently overpredicted. The thrust of this research is to explain the difference between measured and predicted stiffness and damping coefficients for TPJBs, and to provide …
