基于有限元法的自提升运维工装辅助吊装底座结构设计OA

Benefiting from decades of technological accumulation and the impetus of the"carbon peaking and carbon neutrality"policy,China's wind power market has achieved rapid,high-quality development in recent years.However,as the service life of certain wind turbines extends,maintenance issues have become increasingly prevalent.Conventional methods for wind turbine failure remediation primarily involve the use of crawler cranes,truck cranes,or offshore cranes to replace components such as gearbox parts,which are not only inefficient but also costly.In response to this situation,a self-erecting maintenance tooling design suitable for both offshore and onshore wind turbines is proposed.The device can lift the base system onto the turbine via auxiliary hoisting,with subsequent installation completed using ground winches,eliminating the need for other large-scale ground hoisting equipment.The auxiliary hoisting base serves as a critical interface device connecting the auxiliary hoisting system to the turbine.It is essential to minimize base weight and enhance strength through finite element analysis and structural optimization.Following multiple iterations of finite element analysis and structural optimization,the weight of the auxiliary hoisting base structure was reduced from 512.2 kg to 283.7 kg,while the stress at its maximum load point decreased from 497.2 MPa to 401.9 MPa.Both strength and safety factor satisfy the design requirements.
