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

Figure 21

(a) Effects of the trajectory of a moving point force on the deformed shape of the S-S-S-S square plate (Example 1) when the moving point force travels at  = 5 m/s along the trajectory given by Case 1 of (39), where the red arrow indicates current position of the moving point force. (b) Effects of the trajectory of a moving point force on the deformed shape of the S-S-S-S square plate (Example 1) when the moving point force travels at  = 5 m/s along the trajectory given by Case 2 of (39), where the red arrow indicates current position of the moving point force. (c) Effects of the trajectory of a moving point force on the deformed shape of the S-S-S-S square plate (Example 1) when the moving point force travels at  = 5 m/s along the trajectory given by Case 3 of (39), where the red arrow indicates current position of the moving point force.
