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

Figure 9

Simulation results of the vehicle vibrations with respect to eight spring stiffness values and three driving speeds of the vehicle. (a) Displacement and (b) acceleration (red, blue, and black lines indicate low, mid, and high speed, resp., and top and bottom figures indicate peak to peak and RMS values, resp.).
