In spite of the fact that the inertia of the occupant dominates the reactance torque, changes in the rigid body yaw rotational inertia of the wheelchair assembly ([I.
Of these, the rigid body yaw rotational inertia of the occupant and the rigid body yaw rotational inertia of the wheelchair assembly are most significant, i.
The rotational inertia of manual wheelchairs is important because even a slight mass redistribution within the system can cause an affective change in required propulsion effort.
As indicated in Equation (6), the rotational inertia is inversely proportional to the square of the measured resonance frequency.
The configurations are listed in order of increasing rotational inertia and illustrate a highly linear relationship between the masses and inertias.
The reactive torque from the wheelchair rotational inertia is [T.
The highly linear trend in Figure 5 shows that the measured rotational inertia is strongly correlated with the mass of the wheelchair configuration.
