• Description:
  This study assessed whether the under-shoe fluid load during a simulated slip could be predicted based on the size of the worn region. Four shoes underwent an abrasive wear procedure to generate localized wear in the heel. Periodically, fluid pressure sensors embedded in the flooring recorded under-shoe fluid pressures during a simulated slip. Fluid force was then calculated. The film thickness of the contaminant was predicted using a derivation of Reynold's equation for thrust bearings based on the size of the shoe wear region. Linear regression analysis showed that the fluid force was affected by predicted film thickness (p <.0001). Therefore, the fluid film thickness predictions based on the size of the worn shoe region were able to predict the under-shoe hydrodynamics. This model may have potential in determining when worn shoes should be replaced. [Description provided by NIOSH]
