n = test number, = support I position; = support II position; = support III position; = interaction support I × II; = amount of vibration deformation for the set of parameters reported in the nth row; = the maximum vibration deformation for the set of parameters reported in the nth row. All the positions refer to the distance from the reference positions listed in Table 1.
