3.1 Objective of the work
In order to realize the lifting requirements of the elevator, the structural optimization design and simulation of the platform body are carried out to complete the research work on the weight reduction of the platform.
3.2 Main performance index requirements
Platform body shape size:
The platform shape is trapezoidal, the size is about 21m/26m×15m. The height of platform body (without lifting point) is not more than 2.5m. The height of lifting point position is not more than 3.4m.
Platform type: four crane point type.
Working range requirements:
The platform meets the rated load-bearing transshipment requirement under the environment condition of 6 grade sea state, and the local does not produce plastic deformation; it meets the load-bearing requirement under the environment condition of 9 grade sea state, and the local does not produce plastic deformation. Simulation of extreme stress conditions including anti-explosion and anti-impact.
