(a) The first Eigen mode (300 mm longitudinal leg distance) is a longitudinal rocking at 112.33 Hz. The model scale value is 0.262415. (b) The second Eigen mode (400 mm longitudinal leg distance) is a roll mode at 119.8 Hz. The model scale value is 0.216556. Both systems have the same types of modes but with slightly different values due to the different leg separations. |
