Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Research into the influence of machine- and tool-elasticity on the accuracy of formed components requires that the component form is analysed using FEM and measured, perhaps on a co-ordinate measuring machine (CMM), for comparison with the specifications of the component; this comparison would enable the definition of form-errors of the component. A solid modelling strategy, which enables the assessment of manufacturing features of a component within the design cycle, is proposed for nett-shape manufacturing. The approach is supported by an error-evaluation methodology which enables the comparison of the model of the component and the form generated by FE simulation and form-measurement. The integration of the design and assessment is enhanced by the use of an integrated information model which is created by feature extraction and attribute manipulation of solid models.
