摘要
为解决水深45.000 m深海风机钢管桩基础安装作业可靠性差和精度低等问题,对一种新型深海风机钢管桩基础安装用导向架进行结构优化。采用有限元法(Finite Element Method, FEM)与试验相结合的方法,从环境参数与作用载荷、结构形式、作业工况和结构强度与结构稳定性等方面对导向架进行综合研究。经海试验证,优化的导向架的打桩精度与打桩高效性均满足技术指标要求,可大幅提高深海风机钢管桩基础安装作业速度和质量。
In order to solve the problems of poor reliability and low precision in the installation operation of steel pipe pile foundation of deep-sea wind turbine generator pile foundation at a depth of 45.000 m,the structure optimization of a new guide frame for the installation of steel pipe pile foundation of deep-sea wind turbine generator is performed.Combined Finite Element Method(FEM)with tests,the comprehensive research on the guide frame is conducted in environmental parameter and applied load,structure form,operation condition,and structure strength and structure stability.The sea trial proves that the precision and efficiency of pile driving of optimized guide frame meet the requirements of technical indicators,and can greatly improve the speed and quality in installation operation of steel pipe pile foundation of deep-sea wind turbine generator.
