Wheel design and performance evaluation

Our research focuses on accurately simulating and measuring the aerodynamic loads experienced during real-world cycling. A rotating wheel is subjected to two primary forces: axial drag, which resists forward motion, and rotational torque, the equivalent drag opposing its spin. To replicate true riding conditions in the wind tunnel, we utilize motor-driven wheel rotation in combination with a raised ground plane. An integrated test rig enables the simultaneous measurement and direct comparison of these two critical loads, facilitating comprehensive aerodynamic optimization of the cycling wheel.
