WebbAccording to McLaurin & C. E. Brubaker [1] , wheelchair biomechanics involves the study of how a wheelchair user imparts power to the wheels to achieve mobility, and helps us understand how the users body interacts with the wheelchair.

Webbnon experienced manual wheelchair users through applying a marker-based 3D motion analysis technique. Ten healthy male subjects were characterised for three wheelchair configurations, set by adjusting the horizontal axle position of both rear wheels by (3 cm) and (6 cm) posteriorly from the original position set by the manufacturer.

WebbSo this is a combination of factors. First of all, FFB can never be 100% 1:1 with how the actual car behaves because it’s fundamentally backwards. In a car the wheels have a set position and react to the torque provided by the driver. In a racing sim the wheel has a set torque and reacts to the position provided by the driver.

WebbThe slip angles of the wheels are considered to be equal to zero, which is a reasonable assumption for low speed motion during the parking maneuver.
