Optimising Sweeping Techniques for Olympic Curlers
In the sport of curling players sweep the ice in the front of curling stones to increase the distance that the projectiles slide. Their vigorous sweeping raises the surface temperature of the ice thereby reducing its coefficient of friction. The change in ice temperature is dependent on the velocity that curlers sweep the ice, the downward force they apply and the pattern that is swept. The forces and velocities applied by Olympic level curlers were recorded on an instrumented brush. A numerical model was used to determine optimal sweeping pattern based on the curlers sweep force and velocity profiles.
