Embodiment Construction

[0013] A tuned mass damper test method for offshore platforms, as shown in Figure 1, a connection schematic diagram of a hardware-in-the-loop simulation test system, including an industrial computer simulation platform, an electro-hydraulic servo actuator, and a tuned mass damper to be tested , multi-channel analog-to-digital converter, multiple-channel digital-to-analog converter, signal processing device and vibration table. The industrial computer simulation platform outputs the control signal to the signal processing device through the digital-analog output channel, and after the signal processing device performs necessary amplification and level conversion, it drives the servo hydraulic actuator installed on the shear wall to move. The servo-hydraulic actuator drives the vibration table, thereby causing the tuned mass damper fixed on the vibration table to vibrate. The sensor is installed on the vibrating table, the tuned mass damper to be tested, and between the electro-...

Description

technical field [0001] The invention discloses a tuning mass damper simulation test system, which relates to a testing system of a tuned mass damper on an ocean platform. Background technique [0002] Offshore platforms have high requirements for tuned mass dampers, and the parameter selection of tuned mass dampers plays a decisive role in the vibration reduction effect of the platform structure. The cost of installing a tuned mass damper on an offshore platform is relatively high, and installation failure should be avoided as much as possible, causing undue economic losses. Therefore, the tuned mass damper needs to be repeatedly and thoroughly debugged in the laboratory to finally achieve the expected control index. If the tuned mass damper has not been repeatedly adjusted to obtain the optimal parameters, the vibration reduction effect will be poor, and even the vibration of the platform structure will be amplified. [0003] The current method and system for testing a tu...
