[0013] A tuned mass damper test method for offshore platforms, as shown in Figure 1, a schematic diagram of the connection of a semi-physical simulation test system, including an industrial computer simulation platform, an electro-hydraulic servo actuator, and a tuned mass damper to be tested , Multiple analog-to-digital converters, multiple digital-to-analog converters, signal processing devices and vibration tables. The industrial computer simulation platform outputs the control signal to the signal processing device through the digital-analog output channel. After the signal processing device performs the necessary amplification and level conversion, it drives the servo hydraulic actuator installed on the shear wall to move. The servo hydraulic actuator drives the vibrating table, so that the tuned mass damper fixed on the vibrating table vibrates. The sensor is installed on the vibrating table, the tuned mass damper to be tested, and between the electro-hydraulic servo actuato...
