‘Test and CAE working together’
G Rowlands & E R Cawte, nCode International Ltd
Fatigue analysis has been possible in both test and CAE domains for many
years. Whilst the benefits of Virtual Product Development are understood,
and are particularly relevant in fatigue, it remains a discipline in which
both test and CAE tools are used. CAE fatigue tools provide speed and cost
advantages over fatigue testing, and particularly lend themselves to
comparative analyses. However fatigue predictions are notoriously sensitive
to the inputs and simplistic loading assumptions can be far from realistic.
Therefore it is common to base fatigue analyses on real measured loads. It
is also important to compare test-based predictions, analysis predictions
and physical test results to ensure good correlation.
The presentation concludes with a simple example of signal processing
integrated with a CAE fatigue process.

'Modern instrumentation for in-service gear alignment'
J Rosinski - Transmission Dynamics, JR Dynamics Ltd
Northern Power Transmission Research Laboratories UK
This paper considers challenges in planning and conducting measurements to explain component failures and to assist with type testing. Several case studies are given which demonstrate needs for new methods and innovative instrumentation to acquire in-service load information on gears, chains, couplings and shafts.
