Improved blade tip timing measurements during transient conditions using a state space model

Diamond, D.H. (David); Heyns, P.S. (Philippus Stephanus); Oberholster, Abraham Johannes (Abrie) (Elsevier, 2019-05)

Rotor blade condition monitoring is considered an important aspect of turbomachine management, especially with the current trend of systems operating at higher speeds, loads and temperatures. Blade Tip Timing is a non-intrusive ...
A novel method for the design of proximity sensor configuration for rotor blade tip timing

Diamond, D.H. (David); Heyns, P.S. (Philippus Stephanus) (American Society of Mechanical Engineers, 2018-05)

Blade tip timing (BTT) is a noncontact method for measuring turbomachinery blade vibration. Proximity sensors are mounted circumferentially around the turbomachine casing and used to measure the tip displacements of blades ...
Online shaft encoder geometry compensation for arbitrary shaft speed profiles using Bayesian regression

Diamond, D.H. (David); Heyns, P.S. (Philippus Stephanus); Oberholster, Abraham Johannes (Abrie) (Elsevier, 2016-12)

The measurement of instantaneous angular speed is being increasingly investigated for its use in a wide range of condition monitoring and prognostic applications. Central to many measurement techniques are incremental ...
A stochastic hybrid blade tip timing approach for the identification and classification of turbomachine blade damage

Du Toit, R.G. (Ronald); Diamond, D.H. (David); Heyns, P.S. (Philippus Stephanus) (Elsevier, 2019-04)

Blade Tip Timing (BTT) has been in existence for many decades as an attractive vibration based condition monitoring technique for turbomachine blades. The technique is non-intrusive and online monitoring is possible. For ...
