Abstract: The final sensitivity of a
Force-Measuring Bearing depends totally on its strain gauge
distribution pattern and bridge connecting manner when the
optimum depth of strain gauge distributing groove has been
determined. In this paper, photoelastic experimental method was
applied to analyze visually the stress distribution pattern of a
FMB's photoelastic model in detail. Stress distribution curves
under different loading conditions were acquired. The
experimental results point out some defects in conventional
strain gauge distribution pattern and provide reliable reference
bases for the determination of the optimum strain gauge
distribution patterns under different application conditions.
