Measurement of 3-axis forces acting on bottom surface of sliding curling-stone

Abstract

By using MEMS 3-axis force sensors, we demonstrated that we can measure the three axial force distribution when a curling stone rotates and translates on the ice. We cut a curling stone horizontally in order to separate the stone into two parts. Then we fixed the MEMS 3-axis force sensors between the upper and lower parts. We conducted the measurement experiments at the curling rink, and confirmed that our proposed measurement method is effective to evaluate the force acting on the bottom surface of the curling stone.
