Figure 19
The illustration presents a plot with the horizontal axis labeled “x-coordinate [millimeters],” ranging from negative 150 to 0 with an interval of 50, and the vertical axis labeled “y-coordinate [millimeters],” ranging from negative 60 to 20 with an interval of 10. The plot has two main paths of two trajectories: the solid black lines for “Original” and the solid red lines for “Optimised”. The legend at the bottom right identifies the line styles. Each path is marked at five points: a, b, c, d, and e. Labels are positioned near each marker (black for original, red for optimised). For the black line path, the points a, b, c, d, and e are shown at (0, 0), (negative 60, 18), (negative 110, negative 15), (negative 144, negative 55), and (negative 122, negative 20), respectively. For the red line path, the points a, b, c, d, and e are shown at (0, 0), (negative 18, 5), (negative 45, negative 40), (negative 60, negative 17), and (negative 32, negative 22), respectively. Loops or oscillations are visible near the right side of both paths. The red path is generally to the right of the black and more tightly looped near the high-density region. Note: All the numerical data values are approximated.Trajectory of a point on the steering wheel on the XY plane for the original and optimised structure. Source(s): Authors’ own creation
