In the real environment, the SP is exposed to forces, which may cause to move the SP randomly inside water. These motions can be classified into two main types: (a) linear accelerations and (b) rotational motions. The following devices have been utilized to simulate each type of motion and calibrate the sensors as well as the whole system: Shake-table: This machine is generally used to simulate and test the effect of earthquakes on structures and buildings. The shake-table has a highly sensitive single axis accelerometer, which measures the accelerations generated by the table. Figure 32.10a shows the shake-table and the direction of motion produced by it. 2D rotational motors: This device was designed and built to generate rotational motions in two dimensions as shown in Figure 32.10b. It is manually controlled to rotate the SP at certain desired angles. The motors are then placed on the shake table such that linear accelerations are combined with rotational motions at the same time. Figure 32.10c shows the final setup.

Seismic qualification by time-history testing of the equipment using a shake table is a rigorous test method which is considered to provide clear evidence of the capability of equipment to withstand seismic forces. Seismic qualification by time-history testing can be divided into two steps; namely, (1) Resonant frequency test (Free vibration test), and (2) Time history shake-table testing.
