AN ASSESSMENT OF THE INFLUENCE OF ELASTIC, OR PLASTIC, DEFORMATION, ON THE MEASUREMENT ERRORS

Abstract

The reason for choosing this theme is to emphasize the phenomena that occur in a set (measuring device) due to external environmental factors and forces that errors involved in the measurement process. These factors influence the measurement results and their presence can not be seen with the naked eye. Thanks to the progress of last years and helping on software, advanced design, and analysis, the designer have handy ever since the concept of a device able to check the resistance to stresses and deformations that may occur in a structure, model or assembly. Following that verification is able to more easily decide how to strengthen the structure needed, more robust modeling benchmarks or the use of harder materials. These issues are highlighted in this paper and illustrated by finite element analysis of the structure of a measuring device using Ansys software.
