Coefficient of friction ice skates on ice

WebWe obtained accurate experimental data on the resistance coefficients from timing sensors on an ice track and a small accelerometer on the skeleton. A comparison of acceleration from the accelerometer with a numerical model showed a transition from static friction to kinetic friction, as “stick and slip” faded at 6 m/s. Speed and ... WebWe provide an ice friction model for vehicle dynamics of a two-man bobsled which can be used for driver evaluation and in a driver-in-the-loop simulator. Longitudinal friction is modeled by combining experimental results with finite element simulations to yield a correlation between contact pressure and friction. To model lateral friction, we collect …
