Vibration Analysis of Thin Plate Structures Subjected to a Moving Force Using Frequency-Domain Spectral Element Method

Figure 17

Effects of boundary conditions and moving speed on the vibration responses at the center of three square plates when a moving point force travels along the trajectory given by Case 2 of (39). (a)  = 1 m/s, (b)  = 2 m/s, and (c)  = 5 m/s.
