In this paper, a low-cost dynamometer for undriven, steered wheels is described. The dynamometer was produced\r\nto determine whether such an instrumented mechanism is practical. Four S-beam load cells and two opto-counters were used\r\nto obtain all moments, forces, and points of their application. Overturning, aligning, and rolling resistance moments besides\r\nvertical force are directly measured by the load cells. The opto-counters detect wheel angular velocity and steering angle.\r\nThe dynamometer evaluation results showed significant correlation between expected values and measured data with high\r\naccuracy. Wheel dynamic behavior can be defined according to dynamic and kinematic analysis in which relative calculations\r\nhave minimum simplifying assumptions.
