Design Optimization of a Mecanum Wheel to Reduce Vertical Vibrations by the Consideration of Equivalent Stiffness

<div>Simulation results of the vehicle and mecanum wheels. (a) Vertical displacements of the vehicle body (red solid line) and each wheel (blue dash: left front wheel, blue solid: right front wheel, black dash: left rear wheel, and black solid: right rear wheel), (b) vertical accelerations of the vehicle body (vertical red dash line indicates the time when the changeover of rollers occurs).</div>
