In recent decades, China has built more than one hundred seats of ocean platforms on the sea such as Bohai sea, and with the increase of development strength, China will build more ocean platforms. The ocean platform as a large flexible platform structure generally has the characteristics of large volume, low frequency, complex external dynamic load and the like. The ocean platform is used as a development base of deep sea resources such as petroleum and natural gas, and is often subjected to the action of dynamic loads of natural disasters such as wind, wave, stream, ice, earthquake and the like, so that the focus of attention of related scientific researchers in various countries is on how to improve the disaster prevention safety of the ocean platform.
For large flexible structures of the ocean platform, even if the large flexible structures have enough strength, the large flexible structures can generate large vibration response under the action of dynamic loads such as wind, wave and flow, so that the safety of the structures is influenced, and even the ocean platform is damaged. Historically, many ocean platform accidents have occurred, resulting in significant economic and property losses. If the influence caused by the vibration is overcome by only increasing the strength of the ocean platform, the effect is not obvious generally; therefore, when the ocean platform is researched and built, some energy dissipation and shock absorption devices are required to be installed to reduce the vibration effect generated when the ocean platform works in a severe environment, and further the stability and the safety of the ocean platform are improved.
