Recently, the 3500kj large hydraulic hammer core forging developed by Southeast University and Jiangsu Longyuan Zhenhua Marine Engineering Co., Ltd. China First Heavy Group was successfully rolled off the production lineIt marks that China has mastered the design and manufacturing technology of large-scale hydraulic impact hammer core forgings, and has achieved a major breakthrough in wind power core construction equipment.
How to take the first step?
The super-large hydraulic pile hammer is the core equipment of offshore wind power construction. In recent years, with the rapid development of offshore wind power, the capacity of single units is getting larger and larger, and the striking capacity of hydraulic pile hammers and the diameter of pipe piles have become a restriction on the development of the industryBottlenecks, research and development of larger specifications of hydraulic pile hammersImminent。The global market for large hydraulic pile hammersIt has been monopolized by foreign countries for a long time
At the beginning of 2022,Ni Zhonghua, Sun Beibei, Yan Yan, team of School of Mechanical Engineering, Southeast UniversityTogether with Longyuan Zhenhua, we launched the 3500kj marine large-scale hydraulic pile hammer complete set of equipment, and took the first step in the localization of large-scale hydraulic hammer. Combined with Longyuan Zhenhua's rich on-site construction experience and equipment use experience, the team used itIndustry-university-research joint researchThe technical advantages of large-load impact dynamics and fatigue life ** model, the manufacturing heat treatment process of ultra-large forgings and the digital twin model of high-precision pile sinking process have been established, and the core coefficient of the model has been established through engineering data, laying the foundation for the lightweight design and manufacturing process finalization of large-size core forgings (substitute felt seat and substitute ring).
Successfully go offline, forge ahead!
3500kj hydraulic pile hammer core forgingSuccessfully offlineIt is a consortium composed of 8 units, including Southeast University and Longyuan Zhenhua, China First Heavy Machinery, and China Machine ForgingIt became one of only 3 consortiums in the world capable of developing large pile hammers。At the same time as the delivery of the core forgings of the 3500kj hydraulic piling hammer, the consortium signed a joint research and development agreement of "the world's first independent research and development of 6000kj+ super-large hydraulic piling hammer", which marks 6000kj+9The 08-meter super-large hydraulic piling hammer project was officially started, aiming at the goal of creating the world's first offshore hydraulic piling equipment with the largest striking energy, the highest technical level and scientific and technological content.
Serve the country with science and talents.
Climb the peak of science and technology.
Kudos to the research of the University of Tokyo!
