Pedalling cycling mannequin

At race speeds, aerodynamic drag is the most significant factor affecting the resistance to a cyclist’s motion.

When conducting aerodynamic tests with live cyclists, position inconsistencies and asymmetries can have a negative impact on the repeatability of experimental results. 

To counteract this, a life-sized mannequin capable of pedalling on a test rig in a wind tunnel has been developed. The mannequin design consists of an adjustable frame made from telescoping aluminium tubing to provide an adjustable skeletal structure, and a 3D printed outer cladding to produce the required body shape. The mannequin cladding was printed based on 3D scans of athletes provided by Cycling Australia. 

Leg movement is achieved with clevis joints in the knees and hips to create a 4-bar linkage, which mimics pedalling when powered by the bicycle cranks. Articulation is provided via adjustable and lockable joints in the shoulder, elbow, ankle and neck joints.
