Figure 3

2^nd order nonlinear model simulated force examples. Two simulated force trains are shown: 5 Hz doublet train, DT (left column), and 20 Hz constant train, CT (right column), with variations in each of the six individual parameter, B, a, b_o, b₁, n, and k. Only odd numbered parameter increments are included (· -· -1^st, - - 3^rd, 5^th and – 7^th) for clarity.
