Paper Abstract

A study of the working accuracy of length standards is presented in this paper. The relevant formulae are presented and Finite Element (FE) analysis is used to model the effects of thermal gradients the variation of point support position and the effect of a moving load on the deflection and geometry of a length bar. The influence of temperature gradient on the calibration accuracy of length bars is assessed and the best support position to give minimal slope when there exits a temperature gradient is given Some important conclusions are reached and proposed future work is discussed.
