Developing a Computational Model for Predicting Shoe-Floor-Contaminant Friction (PI: Beschorner)


Friction Modeling 1

Friction Modeling 2
This project uses experimental methods to indentify the frictional mechanisms that contribute to slip and falling accidents and then develops tribologically-sophisticated models for predicting shoe-floor friction. Specifically, this study has focused on the ways that fluid contaminants reduce friction through hydrodynamic and boundary lubrication. In addition, the contributions of adhesion and hysteresis to shoe-floor friction are also being considered. The long term goal of this project is to identify footwear and flooring features capable of optimizing shoe-floor friction.

This study had resulted in the following publications (GABL members italicized):

Ladder Climbing Fall Prevention Study (PI: Beschorner)


Ladder Study

Ladder climbing is a frequent task in many different jobs including, but not limited to, construction, maintenance and firefighting. Falling from ladders can cause serious injuries and even death. Correct balance on the ladder is critical to ladder safety. We are currently performing studies to examine the effects of climbing technique and ladder design on climbing stability.

Do you climb ladders in your job? We are currently looking for experienced ladder climbers to participate in our study! For more information, please click here.




Effects of Multifocal Lens Glasses on Walking Balance (PI: Beschorner)


 Bidfocal Study  Multifocal lens glasses such as bifocals or progressive lens glasses distort vision, affect stepping patterns and increase falls risk. We are using biomechanical analyses to better understand these effects. Specifically, we are examining the interaction between aging and the effects of multifocal lens glasses on stepping patterns. Furthermore, we are determining if changes in gait patterns due to multifocal lens glasses are associated with fall risk.


         This study is currently in the preliminary phases.  Conference abstracts include:
